If you want more of something, mandate it, subsidize it and exempt it from regulations. If you want less of something, punish it with taxes and regulations. Put more bluntly, the power to tax and regulate is the power to destroy. This is the First Rule of Government.
No presidency has ever come close to the Obama Administration in employing the rule to advance its ideologies and agendas. No industry has been so favored as renewable energy over the past seven years. No sector has been so thoroughly vilified and subjugated as fossil fuels during that period.
