What do you mean by renewable sources of energy?

Answer 1

it mean that when is done you can always get more

Answer 2

It means that the source of the energy is not consumed by being used. Fossil fuels are not renewable, not in the period of human existence anyway, but wind and solar energy are, because they are continually replenished by energy from the sun. Of course we know the sun will fail eventually and not be renewed, but that is billions of years away so we don't consider that.

Answer 3

An energy resource that is NOT renewable is something like coal or oil. There is only so much in the ground and when that is used there is no more.

Renewable energy resources are replenished when used. This is the case for example, with a renewable like ethanol, which is made from plants, more of which can be grown each year, or hydropower, which depends on water flowing to the sea and is replenished by upstream rains and snow melts each year.

Of course, in both cases, a significant climate change can reduce or prevent the renewing.

Renewable resources are replenishable. Solar, wind, and water are renewable resources that we don't really have to do anything for them to replenish themselves, they do it naturally. Wood on the other hand needs assistance from us if we expect to use it at the rates we do. It is why naturalists do not like logging. In order for us to replenish the trees lost to logging, we plant fast growing trees and in doing so the natural diversity of the forest is lost. It is why there is such a fight to retain the last few old growth forests in America. Ecologically, when the diversity of trees is diminished the forest is susceptible to disease decimating entire regions. The animal life is also forever altered.

Answer 4

renewable sources of energy is a type of energy that can be caused by the gravity of the sun and the moon that can cause verity things likes for instants it can cause the water to move up and down. Renewable sources can be caused of various things, good and bad.

Answer 5

Renewable sources of energy are those that can be replenished naturally in a relatively short period of time, such as sunlight, wind, biomass, and geothermal heat. These sources are considered sustainable because they can be used without depleting the Earth's resources.

Answer 6

Renewable energy is an energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat.

Answer 7

a renewable energy source means that it wont run out
