Wait a minute, this is a little bit awkward…
First the definition of Renewable energy from wikipedia:
is generally defined as energy that comes from resources which are continually replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.
Consequently we use renewable energy because…
Carbon-neutral fuels (including methane, gasoline, diesel fuel, jet fuel or ammonia) are considered carbon-neutral because they do not result in a net increase in atmospheric greenhouse gases.
… and we want to reduce the greenhouse gases. Thus we want a better environment, which means we are nature friendly… Ops now I am confused.
Thanks for putting all this information using one site. Very useful.
