There are a few types of renewable energy such as wind and sun and water. Investing in the equipment needed to make your own energy make be a large investment initially, if you can afford it, it will pay off in the long term. If you can no afford it there are companies out there that offer renewable energy and are priced cheap.
That follows directly from the definition of "renewable energy". A renewable energy is simply one that can be sustained in the long term.
Solar energy is a renewable energy since you can always get energy from the sun and it will never run out, hence the word renewable. Although the sun will explode in around 4 or 5 billion years, solar energy is virtually renewable and will be available for a long, long time.
Chemical energy is both renewable and non-renewable in different situations. When burning fossile fuel, it is non-renewable. But it is renewable with flowers as long as their source remains available. So if the chemical the energy is being produced from is renewable, then the chemical energy will be too.
The sun is a renewable source of energy. Water is not a renewable source of energy. It is a renewable resource as long as the rain keeps on falling on the same place.
Technically, there is no such thing as "renewable energy" - all energy will be wasted eventually, in a way in which it can't be reused. The Sun, too, will run out of fuel eventually. The term "renewable energy" is used, however, for energy sources that can be used for a long, long time - and that is the case with the Sun.
yes hydropower is renewable. renewable means it will be there for ever. as long as water is on the earth we will have hydropower.
As long as the water flows, energy can be generated. It would be renewable.
Chemical energy is both renewable and non-renewable in different situations. When burning fossile fuel, it is non-renewable. But it is renewable with flowers as long as their source remains available. So if the chemical the energy is being produced from is renewable, then the chemical energy will be too.
No, it is renewable, as long as the rain keeps filling up the dams.
A sustainable resource means it will last for ever, or for as long as humans renew the source.
Geothermal energy is considered renewable because it is derived from the heat within the Earth's crust. As long as the Earth's core continues to generate heat, geothermal energy will be replenished.
