wind
1. It is a reasonably constant source. 2. It is 'renewable'. 3. The source of the energy is free.
It depends on where you are and how much wind, sun, etc. you get.
coal cause its abundant, cheap ,intastructre exists and it is a constant supply. It is also a light weight energy source and easy to transport:)
wind, and sun light
Renewable energy sources don't add greenhouse gases to the atmosphere.
solar energy and win energy are the most environment friendly because the are renewable source of energy.moreover they are present in abundance.whereas water is also a renewable source but it is more difficult to renew it.hence solar and wind energy are the best option.
Renewable energy is an energy source that is either in relatively limitless supply, or that quickly regenerates when consumed.So solar, wind and water power are kinds of renewable energy, because they keep coming back even after we've used them.Coal and oil are NON renewable sources of energy, because when they're gone, they're gone.Renewable energy is found in abundance and we must make use of these resources such as solar, wind, hydropower, geothermal to the best advantage. For instance wind energy must be tapped to generate electricity.Renewable energy is any source of energy which can be used or consumed without going into the state of being unusable. Examples of nonrenewable energy sources would be petroleum, natural gas, coal, etc. You will find that everyday fossil fuels are nonrenewable sources of energy. Some examples of renewable energy would be; solar energy, hydro energy, heat energy, heat from friction, etc."A source of energy that is not expected to deplete through constant use or can be replaced or grown within a relatively short period of time."The definition of renewable energy is a resource that you can take and give back,(ex. trees, plants, animals, vegetables.By the name itself it has the definition involved i.e., the source of energy that is renewable is called as the renewable energy.... this is other wise called as the non conventional energy because we have replaced the conventional sources of energy ( like coal, oil, fossilfuel etc.,) to the non conventional source of energy( like solar, wind, hydro, geothermal, tidal, wave, peizo, mhd's etc.,)Energy, of itsself, is never renewable. It always degrades towards hbeing low level heat (entropy). There are however renewable energy sources. In general, renewable energy is identified as the energy that comes from sources that can be replenished or those that cannot be depleted. Such sources include wind, rain, tides, sunlight, waves and geothermal energy.Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat
Renewable energy can't run out. Non-renewable energy WILL run out. Renewable energy is produced at a constant rate, non-renewable is not. Renewable energy is free when the generator is built, non-renewable is not. Renewable energy does not cause pollution (with the exception of biofuels), non-renewable energy does.
Mostly renewable resources are great but a disadvantage about renewable resources that its expensive (more money than nonrenewable resources). And, the newest is not always the best and easiest.
It is renewable energy source (i.e. non exhaustible). It is clean energy source (i.e. not polluting environment). However, its use has limitations of availability of sites with efficient wind speeds and not heavily populated.
Water power, mostly in hydro-electric power plants attached to dams and rivers, is the most common source of renewable energy. Close to 17% of the world's electricity is generated from hydro.
