Why do you say renewable energy resource it energy cannot be created nor destroyed?
You are right: In that sense the term "renewable energy" is a misnomer. What renewable energy simply means is that you can continue using it for a long, long time.
What type of energy does Brazil use?
Ethanol is generally considered a renewable fuel. Brazil is the world's second largest producer of ethanol fuel (behind the United States) and the world's largest exporter. To a lesser degree, Brazil also uses biodiesel, bio-generated methane, and combustible biomass as energy sources - accounting for up to 25% of its energy needs.
Why should society continue to use nuclear energy?
Because we need to. We need to reduce our dependence on fossil fuels and stop producing greenhouse gases. Right now, and for the foreseeable future, say about 50 years, the only viable source of energy in the large scale is nuclear. None of the alternative sources are truly ready for large scale continuous operation. It is true that nuclear power carries risk, but so does fossil power. In fact, it can be argued that the risk of fossil power is greater, in total, than the risk of nuclear power. Unfortunately, various incidents such as Fukushima Daiichi, Chernobyl, and Three Mile Island have been highlighted way out of proportion and people are unnecessarily afraid.
How is solar energy stored and how it is released?
Solar energy is most commonly stored in batteries, depending on when it is going to be used. However, if it's not stored, it is used, or released, right away into the power grid to be used as normal electricty.
Why is it sensible to have a reserve of unused power station?
To back up the on that is being used right now incase it explodes or whatever. Also so that it can be used if the public demand for the power/energy etc becomes suddenly increased without warning.
How is energy manufactured?
Right now, coal and nuclear plants are the main sources of power. There are currently many efforts to shift this to renewable energy sources such as geothermal energy, solar energy, etc. The main reason for why renewable energy sources are currently not the main source is because their output cannot be adjusted during peak hours or other times of higher demand. In many cases, renewable energy plants are more expensive to operate as well. As for non-renewable energy sources, coal and nuclear plants can simply adjust their output during peak hours. The wind may die down or a storm may block the sun during peak hours, reducing the effectiveness of renewable power.
What energy can be recycled?
Energy just changes to different forms, so "recycle" might not be the right word. However, if you mean more like what *sources* of energy can be reused... things like solar power, hydroelectric power, and wind energy are renewable sources. Fossil fuels aren't... or not in the near-term, since it takes a very, very long time to renew those sources.
What is the fastest growing renewable resource?
Wind, solar and wave power. Within the next hundred years - the fossil fuels we depend on right now - will run dry ! Therefore - we will be forced to use alternative energy sources whether we want to or not !
Benefit From A Home Renewable Energy Source?
A renewable energy source is one that comes from things like wind, sunlight, heat of the earth, tides, and other forces. These are called renewable because they come and go without any noticeable impact on the earth. Energy sources like oil, natural gas and coal are considered as nonrenewable because nature takes a very long time to replenish their supply. Reduced pollution is another characteristic of renewable energy. Oil, gas and coal release a lot of carbon dioxide into the atmosphere when they are burned. They also contribute a certain amount of ash and other pollutants that cause problems for the environment. Renewable sources do not have this problem because they are produced naturally. A traditional problem with renewable energy sources is that they are difficult to convert into useful power. Other energy sources like nuclear power have very high concentrations of energy which can create a lot of electricity with just a small amount of fuel. When however, is not as dense and therefore takes numerous wind generators over a large land area to create enough electricity to support a large population. Similarly, hydroelectric power is a good source of energy but it is limited to a precious few rivers and dams that have sufficient capacity. Although renewable energy has been a challenge in addressing the world�s energy needs, many believe it is the energy of the future. As new technologies develop, solar cells and wind generators are expected to become more efficient converting more of the sun�s energy into useful power and less space. Right now a renewable energy source makes sense for the home because of special tax incentives which makes the technology affordable. Although most renewable sources for residential use may not make a home self-sufficient, they can dramatically reduce monthly power bills. Also, during times when the renewable power source is generating a surplus, residents can sell their surplus power back to the local utility who will distribute it over the power grid to other customers. Some nonelectric forms of renewable energy such as geothermal are generally thought of as limited opportunities located near geysers. However, home geothermal visit, he that works by circulating water deep into the surface of the earth to absorb heat which is then radiated into the home. Homeowners who are interested in this type of renewable energy source should check with area providers to see if this type of energy is available in their area.

You are right: In that sense the term "renewable energy" is a misnomer. What renewable energy simply means is that you can continue using it for a long, long time.
Why do you continue to use fossil fuels rather than renewable resources?
Non renewable energy sources like oil, gas & coal are very concentrated forms of energy. All you have to do to release the energy is start them burning and then get out a lot of energy from a relatively small volume. In addition they don't have to be processed where they are found. You can transport them with little trouble. Renewable energy sources like solar & wind are not very concentrated at all. To get a usefull amount of energy from them requires large gathering techniques. These sources also have to be processed into electricity right where they're found. These different characteristics make non renewable energy cheaper to produce. A hundred years ago there was so much oil & gas & coal that no one thought much about it running out and it was so easy to use there was not much interest in the harder much more expensive renewable sources. Nowdays with the polution problem and with fossill fuels getting more scarce and expensive and with advances in technology, renewable sources are looking more and more attractive.
Why do we use solar energy wind energy and hydroelectric power?
People use solar power to heat water and create electricity. When considering the cost of electricity and the available state and federal incentives, solar power is a very smart financial decision. Basically, solar power is the right thing to do for the environment and the economy.There is no other source of energy on the planet more reliable than solar power. There is no pollution or greenhouse effect. It needs no refinement, it's ready to go.
Is solar energy a renewed resource?
solar energy is renewable because it comes from the light of the sun and the sun is a renewable resource if the sun was not a renewable resource we would be dead right now so if the sun didn't make it back to earth in a lifetime then solar energy wouldn't be renewable
Is tidal energy practical everywhere?
No. It is only successful when the land is the right shape to channel the incoming water to a great height. This happens in the Bay of Fundy in Canada, and the River Rance, in France. Not many other suitable places around the world.There are other forms of renewable energy that are easier and more efficient. Wind, solar and geothermal, depending on the right location, will all be major sources of energy in the future.
Your Simple Guide to Green Energy?
Green energy is quickly becoming one of the best ways to reduce your carbon footprint and save money on the costs of running appliances and heating and cooling your home. Solar panels, windmills and other tools are now readily available and can be installed in just one weekend.Types of Green EnergyGreen energy can come from a variety of sources. Solar energy is the most common way to use renewable energy sources, however, and is also one of the most efficient ways of capturing the energy around you. Solar panels can easily be installed on roofs, walls, and on poles around your property to provide clean energy throughout the year. The number of solar panels that you need will vary depending on the size of your home and your personal energy usage.Wind power is also a common way to use green energy. Wind power isn't as accessible as solar energy, and will provide more power to those living on hills and the plains areas of the world. Large open spaces are ideal for using wind power as a source of renewable energy. Geothermal energy is also used in heating and cooling systems as a source of renewable power.Choosing Your SystemWhen identifying the types of renewable energy that are right for your home, it may be a good idea to consider an energy audit. An energy audit can help you identify exactly where you are losing energy and which types of systems would be most efficient for your home. For example, old windows can be replaced with energy efficient models to ensure your renewable energy is used in the best way possible.Creating an energy efficient home can also include using energy star rated appliances and weather proofing your home. Green energy can be used along with more traditional sources, as well. Most solar panel systems are hooked into the main breaker box for the home, allowing solar energy to be used first. Your system can be set up by a professional to ensure the solar or wind power you have harnessed is being used to reduce the energy costs associated with your home.CostsThe costs of switching to a green energy source for off the grid living can vary depending on your personal needs. You can install a few solar panels for just under a thousand dollars, or you can have an entire system set up for several thousand dollars or more.
What is advantages if the Philippines is ready for nuclear power energy replacing non renewable energy resources as its main source of energy i t is good idea?
If the Philippines were to switch to nuclear power, it would answer the power shortage. The Bataan Nuclear Power Plant, if operational, could shoulder half of the country's power consumption. A great disadvantage, however, is the position of the plant. It's constructed right along a fault line. Also, a nuclear accident is also another thing.
Is not saving nonrenewable energy wrong?
it is not wrong it is right just it will it get used up so we will have to find some other type of energy. Anyway there is plenty of renewable energy like solar and wind energy.
