Renewable energy sources are energy sources that are continually replenished. These include energy from water, wind, the sun, geothermal sources, and biomass sources such as energy crops. In contrast, fuels such as coal, oil, and natural gas are non-renewable. Once a deposit of these fuels is depleted it cannot be replenished -- a replacement deposit must be found instead. Both renewable and non-renewable energy sources are used to generate electricity, power vehicles, and provide heating, cooling, and light.
Renewable sources of energy vary widely in their cost-effectiveness and in their availability across the United States. Although water, wind, and other renewables may appear free, their cost comes in collecting, harnessing, and transporting the energy so that it can do useful work. For example, to utilize energy from water, a dam must be built along with electric generators and transmission lines.
Renewables themselves are non-polluting, while the structures built to harness them can have positive or negative environmental impacts. For example, dams may affect fish migration but may also create wildlife habitat
Because renewable sources can be replenished (apex) because we will not run out of them
Because renewable sources can be replenished (apex) because we will not run out of them
This is renewable energy, but some renewable energy is replenished at intervals rather than continually. For example solar energy is only replenished in daylight hours.
Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished).
renewable resource
" Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable(naturally replenished)." - Wikipedia.So no, renewable energy has no harmful gases whatsoever.
what is origin of non-renewable energy sources, including how energy became trapped in these souces
The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy.
A non-renewable resource is one that is used up, that cannot be reused. A renewable resource is regularly replenished or can be reused. Hydro power (renewable) comes from water circulated in the water cycle, and so is continuously replenished by natural processes.
renewable source of energy can be regenerated but non-renewable source of energy can not be regenerated.
We shoud use renewable energy because it helps the earth by caussing less pollution.Today were using fossill fuels which causes pollution wich is bad for earth and us everywere you go their is more fossil fuels in use then renewable energy.Thats why we should use renewable energy.
Renewable energy sources are Solar, wind, Geothermal, Tidal are prime energy sources
