They use a renewable source of energy. Most are constructed using non renewable resources.
If you use renewable energy then you aren't using the energy generated in power stations so fossil fuels aren't being burned to create energy which coats a lot of money, where as renewable energy is basically free apart from the equipment you need to transfer the energy into useful energy such as sunlight is free and so is wind.
Using water as an energy source makes it a form of renewable energy. Using waste as an energy source is also renewable as the waste is being recycled.
Hydrogen is not a renewable fuel. It is a secondary energy source (or an energy carrier) that could be produced using another primary energy source. Hydrogen could be produced using either renewable primary energy source (e.g. solar energy), nuclear energy, or by using fossil fuel (e.g. natural gas)
Solar energy is a renewable energy source, using it, we release less co2 into the atmosphere, thus stopping global warming. (solar powe is good)
Using the energy does not deplete the source of the energy.
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.
One renewable source of energy is solar energy. You can get solar energy from using solar panels. The Renewable Sources of Energy are: Solar Power Hydro Electricity Wind Power Biomass Geothermal
The solar and wind energy are renewable resources. This is an example using the phrase renewable resources.
You need energy to survive
Non renewable energy is energy that you will soon run out on. For exemple Nuclear energy. Renewable energy is energy that you can kept on using and it will never run out! For example Solar energy, Biomass and Wind turbines. These are only a few!
not good using renewable energy willmake the sun dry. that meens that it will be very cold were the sun don't shine. poo
