What political party would be most likely to support the exploration of alternative sources of fuel in order to preserve our natural resources?

The political party that would be most likely to support the exploration of alternative sources of fuel in order to preserve our natural resources would be the Democratic Party. On their platfom they dedicate a space to explain the points from which they consider important in the preservation of the environment:  act to combat climate change, build a clean energy economy, among others. Likewise, Al Gore, considered a candidate of the Democratic Party, is currently an active environmentalist.

On the other hand, Republicans today withdraw the Paris Agreement from the Paris against climate change.
