Renewable energy is a green technology, friendly with no harm to the environment. Any effort or contribution for spreading the use of this safe technology will result in getting pure sustainable energy & saving our mother earth at the same time.

Renewable energy resources are naturally replenished in a relatively short period of time. They include biomass, hydropower, geothermal energy, wind energy, and solar energy. In 2005, about 6% of all energy consumed, and about 9% of total electricity production was from renewable energy sources. Alternative transportation fuels are fuels used for transportation other than gasoline or diesel. Some alternative transportation fuels, such as ethanol and biodiesel, are renewable while others, such as propane and natural gas, are non-renewable.

The United States currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources—such as wind and solar energy—are constantly replenished and will never run out.

Solar

Most renewable energy comes either directly or indirectly from the sun. Sunlight, Solar energy technologies convert the sun’s light into usable electricity or heat. Solar energy systems can be divided into two major categories: photovoltaic and thermal. Photovoltaic cells produce electricity directly, while solar thermal systems produce heat for buildings, industrial processes or domestic hot water. Thermal systems can also generate electricity by operating heat engines or by producing steam to spin electric turbines. Solar energy systems have no fuel costs, so most of their cost comes from the original investment in the equipment. These are now also being used by many home and farm owners who simply build or buy their own very small solar panels and wind turbines which provide a constant supply of energy in their home or buildings. To try to make  solar panels and use renewable energy yourself with lowest cost  we recommend homemade energy.

Wind

The terms “wind energy” or “wind power” describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like. The sun’s heat drives the winds, whose energy is captured with turbines. These are now also being used by many home and farm owners who simply build or buy their own very small windmills and turbines which provide a constant supply of energy in their home or buildings as well.

Biomass

Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called biomass energy.

Hydrogen

Hydrogen also can be found in many organic compounds, as well as water. It’s the most abundant element on the Earth. But it doesn’t occur naturally as a gas. It’s always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.

Geothermal

Not all renewable energy resources come from the sun. Geothermal energy taps the Earth’s internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean’s tides comes from the gravitational pull of the moon and the sun upon the Earth.

Ocean

The ocean can produce thermal energy from the sun’s heat and mechanical energy from the tides and waves.

Hydropower

Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. For more information on renewable energy use and benefits please read the other articles by the same author on  Articlesbase, Ezinearticles or Goarticles etc..

Greenhouse gases are atmospheric gases that trap heat from the sun and warm the planet’s surface. The process is known as “greenhouse effect” and is responsible for allowing earth to warm sufficiently to support life. Although the greenhouse effect is certainly a necessary and very essential part of our earth’s environment if it is to sustain human life, too much of it and there is trouble. The higher the concentration of the greenhouse gases in the atmosphere, the higher will be the Global Warming. Global warming, a gradual increase in planet-wide temperatures, is now well documented and accepted by scientists as a fact.

However the earth’s climate has changed many times during the planet’s history, with events ranging from ice ages to long periods of warmth; the current industrial development and human activities has accelerated the climate change and worsened the damage done to the environment. On Earth, human activities are changing the natural greenhouse effect. Many human activities are responsible for releasing much more greenhouse gases than the earth can possibly sustain. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric CO2. This happens because the coal or oil burning process combines carbon (C) with oxygen (O2) in the air to make CO2. Atmospheric CO2 has increased about 25 percent since the early 1 800s.

High levels of greenhouse gas emissions are resulting in global warming and climate change and this climate change is very likely having an impact now on our planet and its life. Besides resulting in more hot days, many scientists believe an increase in temperatures may lead to changes in precipitation and weather patterns. Global warming may also affect wildlife and species that cannot survive in warmer environments may become extinct. The effects of global warming are very large in number and still there are so many that are still to be found out.

Being carbon neutral is increasingly seen as good corporate or state social responsibility and a growing list of corporations and states are eager to take active part in this direction. Being carbon neutral, or carbon neutrality, refers to neutral (meaning zero) total carbon release, brought about by balancing the amount of carbon released with the amount sequestered or offset. This is an innovative concept which should be adopted by everyone who wants to take his/her personal responsibility for the consequences caused by his/her actions. Becoming carbon-neutral is not only about reducing emissions, but off-setting those that cannot be avoided.

Becoming carbon neutral

When an individual or an organization sets out to become carbon neutral it’s usually achieved by combining the following three steps:

1. Limiting energy usage and emissions from transportation (walking, using bicycles or public transport, avoiding flying, using low-energy vehicles), as well as from buildings, equipment and processes.

2. Obtaining electricity from a renewable energy source

3. Offsetting the remaining emissions that can’t for the moment be avoided or generated from renewable in a responsible carbon project, or by buying carbon credits.

Last but not least, becoming carbon neutral is not the end of the road, but it is a good start in attempting to halt or even reverse climate change and its effect on the Green Planet.

United Nations Conference on Climate Change is the largest intergovernmental conference on climate control that was ever held throughout the history of humanity. Aside from explicit achievements, the largest accomplishment of the Conference is the acknowledgement of the emerging changes in the world arena. Globalization of markets and, as a consequence, global governance in both trade and services, privatization of the energy sector alongside with increasing role of private sector have forever changed the context in which environmental issues should be viewed.

Kyoto Accord or Kyoto Protocol is an amendment to the United Nations Framework Convention on Climate Change that was negotiated in Kyoto, Japan, in December 1997 and was brought into force 90 days after Russian ratification. The amendment represents a new generation of environmental international relations and treaties adopted in the light of globalization. The major aim of Kyoto Accord is to impose control on economic activities related to energy production and foreign investment and in such way minimize the risks for environment. Under this agreement, countries are to reduce emission of greenhouse gases by 5.2%, whereas the long-term perspective is as much as 29% by 2010. The limits are imposed on 6 greenhouse gases: CO2, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride. The economic effects of Kyoto Accord have been an issue of prime concern within the last years and neither one of the parties is able to provide a definite solution as well as outline the potential results of implementation of the amendment. There are three mechanisms in Kyoto Accord that allow for worldwide implementation and are aimed at the environmental goals established by United Nations Conference on Climate Change. The mechanisms are also known as Kyoto Flexible Mechanisms: the Clean Development Mechanism, the Joint Implementation Mechanism, and the greenhouse gas emission trading.

The idea of emission trading is rooted in the concept of unity between countries with Kyoto targets. While every country will be assigned a certain limit within the period from 2008 until 2012, those who do not meet the established quota can sell the leftover amount to countries who emit too much of greenhouse gas. European Union went further; it established specific quotas on CO2 emissions for as much as 11,500 energy intensive plants that are located on the territory of members of EU.

The remaining two mechanisms, Clean Development and Joint Implementation, are aimed to reduce emission of greenhouse gases in other countries. Industrialized countries as part of their long-term plan to achieve reduction in emission of greenhouse gases are to run projects abroad, whereas the results are counted towards their own reduction achievements. While Joint Implementation allow for project implementation on the territory of countries with Kyoto targets, Clean Development is aimed at reductions on the territories of developing countries. By implementing two mechanisms United Nations stimulates reduction in gas emission by transferring technologies to developing countries and developing unity between countries with Kyoto targets. While Joint Implementation will be put in force only in 2008, the Clean Development Mechanism is already successfully functioning since 2000.

The Montreal meeting of the United Nations on Climate Change in 2005 finalized the details of Kyoto Protocol. The 11th Conference on Climate Change was held from 28 November to 9 December. During the Conference 40 decisions regarding long-term cooperative actions and detailed guidance for countries with Kyoto targets have been adopted. Marrakech Accords that is generally referred to as the “Kyoto Rulebook” is considered to be one of the most important accomplishments. The “Rulebook” allows the formal implementation of the Kyoto Protocol. While industrialized countries have started a cooperative action to address the climate change, all members have agreed to proceed with an open dialogue. Basically, on the Montreal Conference implementation of the Kyoto Protocol was ensured. There also were held parallel events touching the following major themes: understanding and preparation for the change, showcasing solutions and sharing best practices, raising awareness and cultural events

www.shcri.com — As an inexhaustible and pollution-free resource, solar energy is becoming the first choice of energy for people. Especially when the traditional energy is becoming less and less, solar energy has become the green energy preferred in the world. According to statistics, when 1% of solar energy on the earth’s surface is transferred into electricity, the transfer rate is 5%. The annual electricity outputs are forty times the global energy consumptions.

At present, many countries are working hard to develop and use solar energy. Europe, Japan and America have planned to put the focus of energy supply security on solar energy and other renewable energy since 2030. It is estimated that the electricity generated by solar energy in 2030 will account for over 10% of the global energy supply and over 20% in 2050. The exploration and development of the solar energy industry will become the main stream of the future energy utilization.

China is rich in solar energy and the theory storage volumes are 1.7 trillion tons of standard coal annually. There are huge potentials on the development and exploration of solar energy. China is located in the Northern Hemisphere, and the distances between north and south, west and east are both over 5,000 km. There is rich solar energy in Chinese vast land. The average daily quantity of radiation yearly in most areas is over 4 kwh/sq and the maximum daily quantity of radiation in Tibet reaches 7 kwh/sq. The annual hours of sunshine are over 2,000. Compared with those countries in the same latitude, China is similar with America but much better than Europe and Japan.

In recent years, Chinese opto-electronics industry is developing rapidly. It has formed the scaled, international and professional industry chain and has many enterprises that can compete in the global market. The market scale of Chinese solar energy industry ranks first in the world. It has the largest outputs and usage volumes of solar water heaters in the world and it is an important producer of solar PV cells. By the end of 2006, the production capacity of Chinese solar water heaters reached 15 million square meters and the collector gross area reached 100 million square meters. The outputs and usage volumes ranked first in the world. China has over 1,000 solar water heater manufactures with the total annual production value of 12 billion RMB. It has formed an entire industrial system and there are over 200,000 employees. Besides, China has widely used solar houses, solar cookers, solar greenhouse sheds and other solar thermal application technologies. At present, there are over 20 PV cell and component producers with the annual production capacity of 1.5 million kilowatts. Suntech Power Holdings Co. Ltd (STP) has ranked in the top 10 in the global PV industry and its aggregate production capacity of PV cells accounts for 60% of the national capacity. To break the restrictions of high purity silicon materials on Chinese solar PV electricity generation products, over 10 enterprises, including Sichuan Xinguang Silicon Co., Ltd, have invested on solar silicon material projects with the annual production capacity of over 50,000 tons. With the improvement of the production capacity and technology levels of Chinese silicon materials, China will form a complete PV manufacturing industry.

In the future, solar applications will be focused on solar thermal powers and solar PV energy. Solar thermal power applications include electricity generation, hot water, drying, air conditioners, and greenhouse and so on. Solar PV energy applications include energy generation, cells, and electric automobiles and so on. Solar water heater is the only commercialized solar technology applied product.

China has become the largest producer and usage country of solar water heaters in the world. The aggregate area has exceeded 90 million square meters and it remains increasing with a speed of 20% to 30% annually. The outputs of Chinese solar water heaters have accounted for over 76% of the global outputs. It is estimated that after Chinese government promotes the solar thermal application work, China will have over 1 trillion RMB of market demands only on solar water heaters in the next 10 years. There are huge potentials.

Solar PV electricity generation is a mature technology at present. It is safe and reliable and has no noises and pollutions. It can acquire energy anywhere and will not be restricted by regions. It doesn’t consume fuels and can be built in a short period. It doesn’t need power transmission lines and can combine with architectures easily. Common electricity generation and other patterns can’t catch up with it. Before 2002, the outputs of Chinese solar cells accounted for only 1% of the global outputs, but since 2004, stimulated by the international PV market, especially German and Japanese markets, Chinese PV industry began to develop rapidly. The outputs accounted for over 10% of the global outputs, ranking the third in the world. It is estimated that the outputs of Chinese PV electricity generation products will be over 1,000 megawatts in 2010.

As the most potential energy in the 21st century, the solar energy industry has huge developing potentials. As it is a new sunrise industry and has a good policy environment, the solar energy industry has high investment values and developing potentials. As present, the solar energy industry is developing rapidly and it has good investment opportunities. But the operation risks and competition risks should be controlled to achieve good investment returns.

3. What Are the Advantages of Solar Energy? Economic and Environmental Benefits of Using Solar Power

Solar energy is a technology which has been around for more than 20 years, and has recently taken the lead as an alternative fuel source, thanks to the high and fluctuating oil prices. This is especially so in these times of global economic crisis with shrinking household budgets and escalating utility bills.

nofollow” target=”_blank” href=”http://10xin.com/reviews/earth4energy.com/” target=”_self”>Making your own solar and wind power for less than $200

The benefits of using solar energy to power your home are well documented. While oil requires expensive exploration and holds consumers ransom by its fluctuating prices, sunlight for solar power is absolutely free. Sunlight is not only free to all, it is also a constantly renewable source of power and is an alternative clean natural fuel source by the gift of mother nature. Solar power comparatively is a better fuel source for us as it does not discharge harmful gases unlike oil. It is no wonder that many households have begun switching to solar power for homes as their key energy source.

In light of the escalating utility bills, many people either have problems paying their bills or drastically cutting back on usage in order to make ends meet. Adopting solar power by building your own solar panels to generate electricity is a proven effective solution to the above problem. And the best part of it is, you need not have to change your lifestyle or cut usage just to pay your bills.

Making your own solar and wind power for less than $200

High cost of purchase and installation of the solar panels used to be the key setback for solar power to take off. But this situation no longer poses as hindrance to solar power development, especially when building solar power for homes with the do it yourself approach. Guides and instruction manuals have become available online which provide specific instructions on how to build your own solar panels for home use. Some better ones even have step by step videos that walk you through the every critical stage as well as a member forum for discussion. The cost of components and materials do not even exceed 200 dollars if you so choose to build it yourself.

In this difficult economic downturn, especially when you are never sure if you will still be able to bring home your next pay check, a dime saved is a dime earned. And being self reliant on homemade solar power is a great start towards being liberated from high escalating costs. In fact, it has been tried and tested by feedback from existing users that those claims of 80 percent savings in utility bills are true.

Attorney-General, Robert McClelland has recently released details of proposed changes to existing personal bankruptcy legislation.

The changes are now available for public consultation and are intended to modernise the current legislation to better reflect what is actually happening in the community. Specifically, it is addressing the fact that we are increasingly seeing a larger number of bankruptcies in relation to consumers with a small amount of assets and low income levels. Where previously bankruptcy was more commonly associated with individuals who were often simply attempting to avoid paying their debts, bankruptcy is now being increasingly accessed by those who have simply found themselves having a hard time financially.

Some major items of the proposed changes include:

• increasing the minimum debt for which a creditor can petition for bankruptcy from $2,000 to $10,000;
• increasing the stay period from when a declaration of intent to file a debtor’s petition is filed to when a creditor may commence action to recover debts from seven to 28 days; and
• increasing the income, asset and debt thresholds to allow more people in financial distress to enter into voluntary debt agreements.

In essence, the Bankruptcy Legislation Amendments Bill 2009 aims to promote proactive discussion, negotiation and remedies. This should see that honest debtors are given a legitimate opportunity to sit down with their creditors and make arrangements for the repayment of debts and creditors are satisfied that they will receive the monies that are due to them without the need to send excessive numbers of individuals bankrupt.

In light of that, the Bill also seeks to toughen the penalties in relation to fraud and other bankruptcy offences so that insincere parties cannot take advantage of the new conditions that are favourable for those who are actually in trouble.

When it comes to renewable energy, wind and solar are the media darlings. Every time I hear renewable energy mentioned on TV or radio, it’s always wind and solar.  If geothermal is mentioned, it’s an afterthought, and said almost under the announcer’s breath.  Why?  Given the immense importance of the United States’ (and the world’s) energy future, this is not the time to complacent.  The stakes are too high as global warming looms large over our collective heads and the era of easily-accessible fossil fuels winds down.  Our transition away from hydrocarbons to renewable energy is way too critical for any of us not to be informed about all available viable options.

Why you ask?  Because informed and motivated citizens equates to political action which in turn starts the flow of money for development.  We are all influenced by the media and public opinion. This is especially true of politicians.  Why do you think they spend so much money doing polling.  It is their way of determining what we, the public, want from them.  We should also be wanting geothermal energy.

Solar and wind are viable alternatives but they have their detractions.  So does geothermal.  But given the facts, geothermal, at the very least, deserves equal billing.  Actually, the US is already the world’s largest producer of electricity from geothermal. A fact that few, outside of the geothermal industry, know.   According to the Geothermal Energy Association, “geothermal power makes up a total of 3.15 gigawatts (GW) of installed capacity in the United States, its largest producer, and more than 10 GW worldwide.” So, while geothermal gets fewer headlines and media attention it actually supplies more mega-watt hours of electricity than either wind or solar.

Geothermal power plants provide what is known as base load power i.e., they produce power at a constant rate, just like coal-fired, natural gas, hydroelectricity or nuclear power plants.  Wind and solar energy are generally considered intermittent power sources.   That doesn’t mean that wind and solar are unimportant, we need all three – four if you add in hydropower.  Geothermal resources are not available everywhere, at least not for power plants.  Home geothermal heat exchangers are used almost anywhere.   

Fortunately, in the US, geothermal development is, albeit quietly, on the rise.  According to the Geothermal Energy Association, “geothermal power projects grew 46 percent last year.  That’s up from about 30 percent growth in 2008.” Furthermore, “If all of the planned projects were to go forwards as planned, an unlikely scenario, the total U.S. geothermal capacity would reach today’s worldwide capacity of 10 GW — enough to meet the power needs of an average 10 million people or supply 25 percent of California’s 2008 power consumption. But advocates believe the ultimate potential to be much larger still.”

As mentioned, not all of these planned geothermal projects will go forward.  Nonetheless, there’s a quite a ground-swell of geothermal exploration and development happening in America and it’s happening right beneath our feet, literally and metaphorically. 

The bottom line is, it is time geothermal energy started getting it’s due.  When, and if, you ever talk about renewable energy keep this article in mind.  Tell your local politicians you care about funding geothermal exploration.  When you see a news report about green energy, send them an email to mention geothermal next time.  Start a groundswell.  It’s our future and the stakes are high. – David Brooks

The Alliance for Climate Protection is a non-profit organization dedicated to educating the public about the climate crisis. The Alliance for Climate Protection’s goal is two-fold. First, they wish to build non-partisan alliances with varied constituencies and individuals to form a coalition to combat the environmental crises. Additionally, they are working to persuade individuals and society to take measures based on scientific facts from research.

Former Vice President and presidential candidate Al Gore, who has been famously outspoken about the dangers of climate change, is the chairman of the board and brings over thirty years of experience to the table.

The Alliance for Climate Protection works within three arenas to focus and disseminate their message. They work with government offices, business communities, and society at large. The Alliance for Climate Protection is dedicated to non-partisan coverage of the issues in order to push through unnecessary political roadblocks and background noise, and instead focuses all of their attention on working together to make the world a better place.

The Alliance for Climate Protection spells out its main goals as follows:

1. Working toward bi-partisan political efforts to create new climate-friendly proposals to reduce CO2 and methane emissions and other greenhouse pollutants. This task is addressed within the Alliance through persuasive education techniques. The Alliance for Climate Protection works to generate wide-ranging support for climate-protection efforts in order that political entities will work sincerely to generate viable solutions. 2. Pushing for United States participation in the creation of a global treaty to reduce greenhouse emissions and pollution. 3. Persuading individuals at all levels to reduce their own carbon footprint and greenhouse emissions.

It is clear that The Alliance for Climate Protection’s main weapon in the fight against climate crisis is collaboration. A grassroots dynamic is cultivated within the organization through their collaborative education and coalition-building efforts. The Alliance believes that working with a diversity of groups across political and social lines is the most effective means to meet shared environmental protection objectives.

The Alliance’s “Repower America” campaign works to spread the word regarding America’s “dangerous reliance” on carbon-based fuels and sets forth the challenge to end our “carbon addiction.” Repower America informs us that this reliance on carbon-based fuels puts America at economic, environmental, and national security risk. They suggest that investments in clean, renewable energy sources can inject new life into the economy and produce savings for the average American, beyond simply reducing pollution. More information can be found at repoweramerica.org. The “We can solve it” campaign and the “This is reality” campaign are two other projects meant to inform the public and generate support for climate protection.

Al Gore and his philanthropy, the Alliance for Climate Protection has entered into an integrated partnership with Dot Eco, to secure and promote the .eco top level domain.

The world is constantly changing but not like in the past few hundred years. Technological advancements are forcing the environment to change in a way that is not at all desirable to human-kind. Though technology has made our lives comfortable to a great extent the same factors of comfort are contributing to making the world a difficult and uncomfortable place to live in.

The machines that cool or heat our homes and offices contribute to global warming that is causing disastrous changes to the climate and the environment as a whole. The climatic changes all around the globe is leading to environmental disasters in almost every country and this should be sounding alarm bells in every home of the world. However, we are still taking things easy hoping for the governments of the world to do something about putting a climate change emergency program in place.

People should learn from the devastating earthquakes, typhoons and tsunamis that are wrecking havoc around the world. The first point in an emergency program should be to educate the people as to the factors that lead to such environmental disasters and how to detect or predict the possible occurrence of one. Then the next step should include lessons on how to prepare for such contingencies.

Knowledge on how to act in times of environmental emergencies will help people improve their chances of surviving and coming out of such a situation with the least amount of damage.

Evidence is pointing to the fact that nature is going to hold man-kind responsible for the degradation of nature and the onslaught of natural disasters is inevitable. Mankind should be prepared to face these disasters if not do something to avert them – if it is not too late already. Greenhouse gases are not just government propaganda. It is a fierce reality and is the main contributing factor to global warming a phenomenon that is likely result in half the globe being submerged under the seas due to the melting of the ice caps at the poles of the globe.

It is believed that no matter what man does now there is no way of averting warming of the globe, it can only be delayed. What is of prime importance now is that man should understand the problems of climate change and how to react in such times. When climate change brings about a rise in the levels of the seas and oceans, forest fires and other disasters man must know the best measures to be taken.

It is important that the governments of every country should set up a contingency plan and a training program to educate the people as to how they should react in the event of an emergency brought on by climate changes. This will contribute to millions of people being in a better position to safe guard their lives and property and will lessen the impact of the environmental disaster.

With the present knowledge acquired by scientists around he world we now have a better chance of surviving –we also have a better choice.

It is possible to have a portfolio which profitably (that’s the key word, is it not?) invests in alternative energy funds. “Green” energy production is expected to be a multi-billion (in today’s dollars) industry by 2013.

The most recently developed wind-turbine technologies have brought us wind-produced energy which is more cost efficient as well as more widespread. More state-of-the-art wind energy technologies are typically more market competitive with conventional energy technologies. The newer wind-power technologies don’t even kill birds like in days of old! Wind energy production is a growing technology, and companies engaged in it would make up an excellent part of a growth or aggressive growth portfolio.

Next to consider are solar cell, or photovoltaic cell, technologies. These are to be found implemented in pocket calculators, private property lights, US Coast Guard buoys, and other areas. More and more they find their way onto the roofs of housing and commercial buildings and building complexes. Cost is falling. Their energy efficiency (the ratio of the amount of work needed to cause their energy production versus the actual energy production) is steadily on the rise. As an example, the conversion efficiency of silicon cells has increased from a mere four percent in 1982 to over 20% for the latest technologies. Photovoltaic cells create absolute zero pollution as they are generating electrical power. However, photovoltaic cellls are not presently as cost effective as “utility produced” electricity. “PV” cells are not [capable at present for producing industrial-production amounts of electricity due to their present constraints on space. However, areas where photovoltaic cell arrays could be implemented are increasingly available. In sum, costs are going down while efficiency is rising for this alternative fuel technology.

Many alternative energy investment portfolio advisors are confident that alternative energies derived from currents, tidal movement, and temperature differentials are poised to become a new and predominant form of clean energy. The French are actually fairly advanced at hydro power generation, and numerous studies are being made in Scotland and the US along these sames lines. Some concerns center around the problems with the deterioration of metals in salt water, marine growth such as barnacles, and violent storms which have all been disruptions to energy production in the past. However, these problems for the most part seem to be cured through the use of different, better materials. Ocean-produced energy has a huge advantage because the timing of ocean currents and waves are well understood and reliable.

Investments in hydro-electric technology have grown in the last two decades. Hydro-electric power is clean; however, it’s also limited by geography. While already prominent as power generation, the large, older dams have had problems with disturbing marine life. Improvements have been made on those dams in order to protect marine life, but these improvements have been expensive. Consequently, more attention is now being paid to low-impact “run-of-the-river” hydro-power plants, which do not have these ecological problems.

The reality is, the energy future is green, and investors would do well to put their money out wisely, with that advice in their minds.
