Solar thermal (heat) energy is a carbon-free, renewable alternative to the power we generate with fossil fuels like coal and gas. This isn't a thing of the future, either.
Renewable energy is energy obtained from sources that can be renewed. Wind, sunshine and water power are the most common. Non-Renewable energy is energy obtained from sourcesâ¦ that cannot be renewed. Examples of these are fossil fuels like coal, oil and natural gas.   A: You can use renewable energy resources for ever, they never run out! Just like solar energy because the earth will keep on having sunlight from the sun.
