Japan is a densely populated country, and that makes the Japanese market more difficult compared with other markets. If we utilize the possibilities of near-shore installations or even offshore installations in the future, that will give us the possibility of continued use of wind energy. If we go offshore, it’s more expensive because the construction of foundations is expensive.

But often the wind is stronger offshore, and that can offset the higher costs. We’re getting more and more competitive with our equipment. The price—if you measure it per kilowatt-hour produced—is going lower, due to the fact that turbines are getting more efficient. So we’re creating increased interest in wind energy. If you compare it to other renewable energy sources, wind is by far the most competitive today.

If we’re able to utilize sites close to the sea or at sea with good wind machines, then the price per kilowatt-hour is competitive against other sources of energy, go the words of Svend Sigaard, who happens to be president and CEO of the world’s largest wind turbine maker, Vestas wind systems out of Denmark. Vestas is heavily involved in investments of capital into helping Japan expand its wind turbine power generating capacity. It is seeking to get offshore installations put into place in a nation that it says is ready for the fruits of investment into alternative energy research and development.

The Japanese know that they cannot become subservient to the energy supply dictates of foreign nations—World War II taught them that, as the US decimated their oil supply lines and crippled their military machine. They need to produce energy of their own, and they being an isolated island nation with few natural resources that are conducive to energy production as it is defined now are very open to foreign investment and foreign development as well as the prospect of technological innovation that can make them independent. Allowing corporations such as Vestas to get the nation running on more wind-produced energy is a step in the right direction for the Japanese people.

The production of energy through what is known as microhydoelectric power plants has also been catching on in Japan. Japan has a myriad rivers and mountain streams, and these are ideally suited places for the putting up of microhydroelectric power plants, which are defined by the New Energy and Industrial Technology Development Organization as power plants run by water which have a maximum output of 100 kilowatts or less. By comparison, “minihydroelectric” power plants can put out up to 1000 kilowatts of electrical energy.

In Japan, the small-scaled mini- and micro-hydroelectric power plants have been regarded for a considerable time as being suitable for creating electricity in mountainous regions, but they have through refinement come to be regarded as excellent for Japanese cities as well. Kawasaki City Waterworks, Japan Natural Energy Company, and Tokyo Electric Power Company have all been involved in the development of small-scale hydroelectric power plants within Japanese cities.

In the United States and most parts of the earth, fossil fuels have shouldered much of the load for providing energy. Increased demands cause to population growth and expanding industries need more and more energy. Also, since many countries do not produce much oil and gas for their needs they are dependent on other countries for much of their supply. Now a days this has resulted in baseless price fluctuations, which have had a spectacular affect on our everyday lives. There are many substitute to fossil fuels — not all are virtual, but here are some alternative energy sources that have been proven to be costly in the past, and still have quite a bit of future potential.

Nuclear Power – In the United States there are over 100 nuclear reactors, which presently return around 20 percent of our energy needs. Atomic power produces over 75 percent of France’s energy, and large amounts for many other nations. There have not been any atomic power plants built in the United States since the 1970′s, but in 2007 a company in New Jersey filed a license to build a new plant, and other companies have also applied for licenses. Because of past issues associated with nuclear waste, nuclear energy often has a stigma attached to it, but we have come a long way in our ability to safety store waste temporarily and then reprocess the waste for additional energy or medical isotopes.

Hydroelectric Power – This sort of power is widely used in many parts of the United States. Electricity is generated by dams when high water pressure flows through turbines and causes them to rotate. Grand Coulee Dam, located in Washington State, is the nation’s largest hydroelectric benefits. and is one of the essential reasons why Washington State generates approximately 30% of all the hydroelectric power in the country. There is still plenty of possible for increased hydroelectric power, especially since only a small portion of the dams that live were reinforced for power generation. As a new method, more efficient systems come online, and more energy is produced by existing systems, then more hydroelectric power will be useable.

Solar Power – This natural energy source has been providing passion for humans throughout the ages. The problem has always been in developing ways to accumulate and harness this energy so that it can be used smartly long after the sun has gone down. Solar PV panels are used to collect sunlight and turn it into usable electricity. unluckily, today’s accepted solar panels are only able to convert a little over 15% of the sunlight energy into electrical power. skillful progress continues to be made, though, making this one of the most hopeful methods of substitute energy usable today.

Wind Power – Some areas are far more better suited for using wind power than others since wind speeds changes vastly all over the world. Wind power is produced by wind turbines or windmills. These windmills can orbit in size from small private units that provide some or all of a home’s energy, to large commercial wind turbines distributed in wind farms to power full communities. In the United States, California and Texas currently generate the most wind energy, but there is still much untapped potential not only in these states, but all across the country.

Each of us has heard the phrase “don’t put all your eggs in one basket” probably many times over the years. Even so, we have relied on fossil fuels for most of our nation’s energy needs for far too long. Fossil fuels are necessary, but alternative energy sources must be developed so that our country can have a more diversified approach to our energy production. The energy sources mentioned in this short article are just a few of the many alternatives to fossil fuels.

On point goes to the environmentalists’ corner, though more complications will have to be burdened by those who are pushing climate bills for the United States in the 21st century. The great oil spill due to the collapse of BP’s oil rig brought forth some immediate concerns for the ecology and the environment, and would certainly make noise in the entire industry as well as within the government for quite a time.

If and when the weather does not cooperate, leading the massive oils spill to reach the coastal states, its environmental impacts will last for a very long time or could even be irreversible. Prior to the failure of the oil rig, passage of climate bills in 2010 was by no means a certainty. Many issues that are political and economically related are weighed heavily on the legislators’ minds and are even considered by the Senate. Progress was slow indeed.

Score one in the corner of the environmentalists, but just add additional complications for those trying to push through climate bills to finally bring the United States into the 21st century. The massive oil spill created by the collapse of BP’s oil rig created immediate ecological and environmental concerns, but the repercussions were sure to reverberate throughout industry and government for some time.

Republicans tend to favor an increase in offshore oil drilling. They look at it as a way of achieving energy independence, even when every barrel of oil created in such a way is automatically floated on the open market pool anyway. Purchasers do not really have that much option to buy from a particular source. As such, the notion of oil independence is something of a misnomer.

Advocates of alternative energy are seizing on the issues created by the BP oil spill and calling for climate bills to be tough and, to include additional capital for wind farms and solar projects. As a means of trying to push climate bills through, some suggest that funding should be diverted toward nuclear power projects and “clean coal” to try and entice enough politicians from both sides of the debate to sign up.

Climate bills being considered by Senate committees in 2010 are a far shadow of the really extensive legislation proposed by the other House. The ACES Act, as passed in 2009, suggests a comprehensive “cap and trade” option, to force down carbon emissions across the country.

The BP disaster could not have come at a worse time for proponents of climate change legislation. Pres. Obama has said that climate bills are the cornerstone of his administration’s policy. Countries from all over the world are calling some action from the U.S. as it is one of the biggest producer of emissions that cause global warming that lead to climate change.

The Kyoto protocol, ratified by the majority of countries around the world, agreed that climate change could not be controlled comprehensively unless some form of stringent action was taken by each country. While the European Union is far ahead of the majority of other countries, the United States of course fails to ratify Kyoto.

Most likely, climate bills are going to emerge from the US Congress by 2011, as soon as the midterm elections will be done. Meanwhile, the BP disaster is just another example of how fragile our energy infrastructure is and how each organization should ensure that it is not overly dependent on expensive forms of energy for its ongoing existence.

Wind Power as a Viable Solution to Meeting Alternative Energy Needs

Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs—while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.

Electric bills and fuel bills are rising steadily—but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient.

In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to “go primitive”, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment. Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers.

In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total “green” energy systems’ costs.

In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called “net metering laws”. The rates that they are being paid by the local power companies for this energy are standard retail rates—in other words, the homeowners are actually profiting from their own energy production.

Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government,” the Energy Department’s Craig Stevens says. And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals.

“We should [only have to] pay you the wholesale rate for … your electricity,” according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy. However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, “It’s quality power that strengthens the grid.”

Green living entails using green technologies to produce green energy. Green technologies imply harnessing the eco-friendly natural resources like solar and wind power to produce energy in order conserve the earth and its environment.

Solar energy is one of the major sources of renewable energy. It involves using the power of Sun to generate energy. Solar energy is an ideal replacement for perishable energy resources like coal and petroleum that are being used for decades. The need for replacing the traditional energy resources arises because of the dwindling stocks of such energy and their harmful impact on earth’s eco-system. Major part of solar energy is absorbed by the water bodies like oceans and rivers and other processes like photosynthesis on the earth. Solar energy is utilized to produce water cycles, food and life sustaining atmosphere that is essential to support life on earth. Solar energy is now being utilized on daily basis to produce different forms of energy. Solar panels are used to convert the power from sun into electrical energy, which is then used to run different electrical appliances in the homes and the workplaces throughout the world. Solar panels are also used to convert the solar power into heat energy, which is then utilized to heat the water in the water heating systems like boilers and geysers. Solar cookers are used to convert the solar power into heat energy, which is then used for cooking and heating foods. Solar cookers are also utilized for heating and boiling water, pasteurization of milk and drying food items. The temperature generated by these cookers can range anywhere between 90 to 150 degrees celsius.

Wind energy is another clean and renewable source of energy that involves harnessing the power of wind. Large numbers of wind turbines are built throughout the world in order to capture the kinetic energy of wind, which is then converted to electrical energy to power industrial units and large residential areas. The latest technology called vertical axis wind turbines that just require to be pointed towards the wind’s direction in order to generate electricity for homes is gaining in popularity across the world. Home based wind energy system includes a wind turbine and generator that are mounted on top of the tower and the associated controls and equipments that are located in separate cabin. There are three wind energy systems that can be used for generating electricity for home. First is Off-Grid or Stand Alone system. This system is installed when your home is not connected to the grid. You will only use the electricity generated by the Off-Grid system. Second is Grid-Tied or On Grid system that comes with battery back up. With this system, you can use the power supplied by grid as well as electricity generated through the wind energy system. With battery back up you can store the energy and use it in case of a power outage. Third is Grid-Tied or On Grid system without battery back up. This works the same way as the second system except you can’t use it during the power outage as there is no back up system installed.

Solar energy and wind energy are the two clean and renewable sources of green energy that is essential for green living.

Alternative energy, whether it is used to replace fuels such as coal, or to reduce our reliance on petroleum based fuels; alternative energy is one of the most important issues facing society today.
The two most common types of alternative energy are:
* Wind power
* Solar power

Both of these alternative energy sources are harnessed from natural resources, and as such are completely free. Only the equipment and technology cost money, and over time as we advance the costs should be reduced.

It is these free sources of alternative energy that we should be pursuing with the most fervency, so that, eventually, energy can be available to all regardless of income. Below we will take a look at these two most common sources of alternative energy.

Wind Power

Wind power, while a free source of alternative energy, would be the most costly type of renewable energy to power our nation. This is largely in part to the fact that we must first place wind turbines across the country, in enough numbers to provide electricity to communities nationwide, even in areas where the wind velocity is not as strong. The cost of building enough of these turbines to harness the wind’s alternative energy would be staggering.

Also these wind turbines are very unsightly and would ruin very beautiful and scenic parts of the country. It should also be noted that they only produce power 1/8 of the time that they are running. That is not very efficient, but we are on the right track, things just need improvement.

Another problem I see with wind turbines is the amount of profit many companies stand to make for putting them in. Individuals are making millions off of this and that is just not right when our well-being is at stake.

However, if you’re interested in using wind power as your own source of alternative energy, it is a viable option. Many farms and rural communities use these wind turbines to power themselves. In smaller numbers, the cost of building the turbines pays for itself relatively quickly. But wind energy is only one form of alternative energy. Next, we will look at using solar power as an alternative power source.

Solar Power

Solar power is alternative energy derived from the power of the sun. Solar energy is also completely free, except for the cost of installing the equipment necessary to convert the sun’s rays into usable electricity. This equipment is becoming less and less expensive every day. Solar power generally ends up paying for itself within the first few years.

The equipment needed to use solar power as an alternative energy source for your home can be bought at virtually any home improvement store, and can usually be installed in just a few hours. If you don’t feel comfortable doing it yourself, there are a great number of contractors available who can install your solar panels and generators for you.

Regardless of which type of alternative energy you choose to use in your own home, the fact remains that we must find a renewable source of energy soon, or be at risk of losing the few natural resources we have left to burn. Contact your Congressman today, and ask what is being done to find a good source of alternative energy; and what you can do to help.

With a new emphasis on alternative energy, it is no wonder people all over are starting to use the benefits of solar power. It is certainly an everlasting energy source, as long as there is the sun, there will be available solar power.

One advantage of this alternative power is that it is a very available energy source for electricity. However, there are also some disadvantages to solar energy that you should be aware of.

It’s best to research all of the advantages and disadvantages of solar power before you actually have a system installed on your home. If the advantages outweigh the disadvantages, then you’ll know that setting up your home for solar enerfgy is the right decision for you.

The Short-term Cost of Solar Energy: A Disadvantage

The sun’s rays are free, they beat down naturally on earth, however, it costs a lot of money to actually set up solar cells and other solar equipment on your home. Just the equipment to power a pool can cost thousands of dollars. It is very important that you diligently research all costs associated with powering any part of your home before you do it.

Ask questions about warrantee’s, how much repairs cost if necessary etc. One great long-term cost advantage to going solar is that you will never have to pay another bill from your power company.

Talk To Neighbors Who Use Solar Power

The best way to learn firsthand the advantages and disadvantages of alternative power is to talk to people who actually have solar cells set up on their homes. These people have nothing to gain by lying so you should get a very honest account of what it means to live off of solar power.

If you live in the suburbs you should easily be able to find someone in your neighborhood that already has solar power. Another great way to learn more about this enrgy source is to go to a store that sells the solar equipment and ask them if they have any testimonials or a customer list. Get a hold of these poeple and ask questions about solar energy.

Make sure that you contact more than one person. That will not only help you understand the advantages and disadvantages to solar power, but it will also give you a chance to get feedback on that store’s level of service.

You may hear responses like, “It’s very expensive to set it up initially but otherwise it’s great,” or, “I’ve saved so much money from going solar over the years it’s not even funny.” However, you may also hear things like, “If there’s no sun, you don’t get that much power. The reserves do not last that long and I’m sick and tired of all this solar nonsense.”

If you get mixed reviews from several people, make two columns and add the two up. Then, you should get a good idea how people feel about their alternative power.

Read Solar Power Forums

Forums are another great tool to hear, or read, firsthand how people feel about their solar setups. When people post things on a forum, they know it’s anonymous so you should also get a very honest representation of the advantages and disadvantages of solar power. Compare the list you get from the forums with the list you got from talking to people and then make your decision.

As you can see the most important aspect to buying solar power for your home is talking to other people, doing your own cost research, and then determining if it is right for you. Correctly weighing the advantages and disadvantages will help you make the choice that is right for you.

If you plan to live in your home only for another year or so, it may not be worth the cost, but on the other hand you could end up saving yourself a lot of money in the long run by going solar if you stick around for five years or more.

If you want to understand the various forms and sources of alternative energy, read on.

Sometimes called renewable resources, alternative energy does not need fossil fuel or even the splitting of the atom to be produced. It is called renewable because the sources of it are constantly being produced. It does not cause the pollution that oil and gas cause.

This kind of energy is not really new. What is new is that we now categorize these forms of energy as alternative energy.

The forms that alternative energy may take are fuel cells, geothermal energy, wind power, biomass, hydro electric energy, solar energy and water energy such as wave and tidal energy.

Fuel cells as a type of alternative energy is usually associated with electric cars, or hybrid cars. Electro chemical devices produce power through a chemical reaction. The primary benefit of fuel cells technology is that power is produced without the production of harmful pollutants. They are still very expensive to produce, however.

Geothermal energy can be a powerful source of energy. It is ideal for small scale use to heat houses, businesses and small industry. On a larger scale, geothermal plants extract the heat from the earth and use it to create steam to power turbine engines.

Wind turbines produce energy using the same principal as windmills. Blades are moved by the wind, and a shaft attached to the blades rotate a generator that produces energy. This energy is stored in batteries. Wind is, of course required to run this type of alternative energy, so the more wind you have the better it will work. Sites where there is a lot of wind, such as open farmland are good for wind turbines, or other locations that cannot be reached by powerlines.

Biomass is organic material that can be converted to fuel. There are many types, such as animal waste, crops and grains, wood and other byproducts from mills and forests as well as from aquatic plants. One type uses the matter to burn to produce steam power; another type transforms the matter into a gas or liquid.

Solar energy is probably the most well known form of alternate energy. It is the safe and efficient use of the heat from the sun to form energy.

Energy from water. Hydroelectric energy is the energy produced by dams.The movement of the water causes turbines to generate power instantaneously. The initial cost of a dam is very high, but after that the power is free. Tidal energy works on the same concept as dams. The turbines are put directly in the water and the motion of the tides over them powers the turbines. Wave energy uses the motion of the waves in the same way.

Those are your basic types of alternate energy sources.

As the worlds energy crisis becomes more and more obvious, the importance of reducing society’s dependence on non-renewable energy sources like fossil fuels is more and more urgent. Non-renewable energy sources are on the way out. Renewable energy sources, such as a home wind turbine, can put out energy cleanly and without using up rapidly depleting sources. There are three types of renewable sources to look out for: solar, hydro, and the most promising, wind.

The sun is the most abundant energy source on Earth. It’s free and unlimited. Solar power solutions are currently being developed to be more cost efficient and widely available. Many predict that this will be one of the biggest energy suppliers in the future. Solar systems are environmentally friendly as well as very low maintenance. The sun has always been the main supply of energy to the earth and hopefully in the future we can harness this great power.

Hydro energy is currently the most popular renewable energy source. In the future however, this is likely to change. Although hydro energy is clean and efficient, it is extremely detrimental to local environment and ecosystems. Although hydro energy is being developed to operate cars and appliances.

By far the best and most promising solution is wind energy. For around $200 dollars, anyone can set up a small home wind turbine and begin harnessing the wind to power their home. wind is completely clean and efficient. Before wind was too expensive to employ at the consumer level but with recent technological advancements, virtually anyone can begin using it. There is a low start up cost and very little maintenance. The future is here when it comes to wind power.

While the financial crisis may have sidelined renewable energy as a viable choice for the average homeowner or small business owner, the same forces that created this downturn may setup a perfect storm for renewables to come surging back and bring employment opportunities with them.

A lack of available financing, restricted household budgets, and plunging business profits put a damper on the change to renewable energy since this recession began in late 2007. Once oil and natural gas came crashing down from their summer 2008 highs, renewables such as solar and micro-wind have suffered from a poor dollar cost comparison with brown energy.
Despite a clear public desire to switch off carbon-based energy, many found renewables difficult to justify in terms of a personal utility choice. System sales stalled and a question mark hung over the industry’s future. Analyst recommendations for solar and wind companies followed their stock prices: down. And many who had seen a future career move into renewables found themselves dealing instead with the realities of a severe economic downturn. While the desire for renewables continued, the means of fulfilling it was weakened.

Today a confluence of factors may be shifting once again in favor of renewables, bringing back a surge of new system sales, investment and importantly, employment. The price of brown energy is cycling up again with crude oil back to $50/barrel, home heating oil at $2/gal and natural gas seems to have formed a bottom at $4/MBtu’s. On the investment front, significant commentary by economists and stock analysts about the lack of investment in new oil and gas production capacity is pointing at supply shortages on the 5 years horizon. In the near term, China’s internal stimulus packages are widely recognized to be effective in restoring economic growth at the same time that the American economy is seeing glimmers of positive news. Blocks and blocks of foreclosed, abandoned and scavenger-gutted housing stock in cities across America present a chance for restoring them with renewable energy technologies. And perhaps most telling, the new administration has made renewable energy a centerpiece of its agenda and declared it off limits in budget negotiations with congress. This welcome stabilizing of the recession points to increased energy consumption as the world economy re-inflates, with increased prices and employment following on its heels.

So how to ride this new wave of opportunities in renewable energy? The same as you ride any wave: with a surfboard and some skill, remembering to add in a touch of bravery.  In the case of changing careers into renewable energy, the “surfboard” is basic knowledge about the science and technology of solar, wind and geothermal, how such systems work, the skills used in assessing a residential or commercial site, the financing and  ROI calculations, and system design and installation details. This set of knowledge and skills is the foundation for understanding and working with renewable energy.  Complementing this knowledge,  an understanding of the industry and how it is structured and the wider trends at work in and on it enables one to make informed choices.  Rather than riding the same wave as everyone else, a broader education brings a broader view and the ability to plan well for the future. As with any career move – one made by choice or by having the choice forced upon us – a touch of bravery overcomes the inertia that so often prevents us taking the first step.

To get the career equivalent of the surfboard, seek out education and training options that will get renewable energy knowledge and skills in your hands sooner rather than later. However, try not to set yourself up to be overwhelmed with the transition by planning multiple classes spread out to give yourself time to absorb and use what you learn. The brown energy infrastructure has taken 150 years to be build up: it won’t change overnight and most people alive today have never dealt with “energy” beyond the electrical outlet in the wall. An increasing number of community colleges, solar and wind equipment manufacturers and training companies are offering classes and workshops in renewable energy. Ranging from hands on training geared for technicians to install solar panels and erect wind turbines to courses in renewable energy sales and marketing, these classes will add renewable energy knowledge and skill to your resume and extend it beyond your previous career. 

With a new, upward trend in energy costs and strong motivation to re-tool America’s buildings off brown energy, $15 billion per year promised by the new administration and signs of economic stability on the horizon, now is the time to pursue the many training providers across the country for knowledge and skills in renewable energy.
Few other recessions in the post World War II era have been as severe as this one. Nor have they had such a perfect storm of conditions built-in to bring about an explosion of new economic growth to end them. Catch the wave. The time to train for the coming change from the brown energy of the past to the renewable energy of a recovered economy is now.
