Coal is mined, oil and natural gas drilled, uranium mined. Wind and solar energy, tidal and ocean current, there to be taken. Hydro power, build a dam and wait for rain to fill it up.
Oil
When electromagnetic energy from a heat source interacts with its environment, it is being absorbed by the objects in the surroundings. This absorption causes the particles in the objects to gain energy, resulting in an increase in temperature.
Any energy source that is renewable does not increase carbon dioxide (CO2) levels in the environment. Examples of renewable energy are solar, wind, hydro, tidal and wave, geothermal and biofuel.
Geothermal energy is a free, natural resource. It is a renewable energy that will not run out and does not harm the environment.
The source of energy driving this is the heat energy coming from the Sun.
Not really. Even endothermic (energy absorbing) processes that appear to have no energy source take that energy from their environment. This can often be measured as a temperature drop.
tidal energy is good because it is a renewable source that doesn't pollute the environment. It is often used to make electricity.
Cells, like humans, cannot generate energy without locating a source in their environment.
Because its a renewable source of energy and also because it creates no pollutants - ehlana11 -
solar energy and win energy are the most environment friendly because the are renewable source of energy.moreover they are present in abundance.whereas water is also a renewable source but it is more difficult to renew it.hence solar and wind energy are the best option.
There is no engine that runs on water as its energy source.
Plants convert solar energy (the primary energy source in the environment) into food and fuel.
