If you can regrow the plant, then you can renew the energy obtained from it. Of course it is not all gain, you have to put some energy in to prepare the soil, fertiliser, etc.
It is A renewable source of energy.
Renewable energy helps the planet because renewable energy doesnt waste our planets resources e.g. crude oil. Renewable energy will never run out so we can keep using it e.g. wind farms and hydroelectric dams
Energy is not renewable. The sources to make that energy may be. After the initial cost of plant and equipment some sources are practically free so the only costs are maintenance costs..
No, cotton is a plant. If it is burnt as biofuel it is a form of renewable energy.
It provides renewable energy for human populations
Sources of energy are termed renewable and non-renewable. Electricity can come from many sources including power plants, wind farms, hydroelectric plants and solar panels. Power plants that burn fossil fuels are using non-renewable fuel sources, but energy from solar panels use renewable energy. A power plant can use biofuels, which are renewable.
It provides renewable energy for human populations
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.
Geothermal is considered a renewable resource as it uses water and the earth's heat. Both of these are inexhaustible. However, if the water near the plant is exhausted (no more water in that area, but there is no less water than before), then the plant must be moved. It is still generally considered a renewable source of energy.
The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy.
A plant and plant based material is considered renewable.
A renewable resource is one which will be replaced after it is used. Wind energy is renewable because the wind will return tomorrow. Trees are renewable if you plant them again. So, fruit trees are a renewable resource.
