Where do you think the government should put the greatest support: solar energy, wind energy, clean coal, oil exploration, gas exploration, or a combination of sources? are there other efforts that should be explored?

I believe that the government should focus on supporting solar and wind energy over anything else.

Explanation:

There are two reasons why I believe the government should put the greatest efforts in solar and wind energy.

First of all, obtaining coal, natural gas, and oil is cheap because the governments and companies have put great amounts of money in research to produce it at the lowest possible costs. Therefore if we fund research with the same model, we are going to obtain cheaper costs. The second reason is that they are renewable and 0 pollution sources of energy, unlike coal, gas, and il. Also, we can create engines like the ones electric cars use, to all transports.

There are other efforts like nitrogen, geothermic energy and my favorites, gravitational rejection impulse energy and electromagnetic energy like the one the Japanese shinkansen uses.
