Because, as I have said more than I like recently, you can argue climate change until the Sun goes out, but you can't argue the Law of Conservation of Mass and Energy. We as a planet are a closed system running a finite resource through a linear energy production system, and all requests to justify it have gone unanswered. It's...unconservative. You and your administration actually have the power to change this and make Congress listen.
Congress is to introduce legislation to end America's dependence on carbon.
Congress is to improve funding to the sciences, so R&D of renewable energy systems can be commercialized.
Congress will end wasteful oil and coal subsidies.
And finally, once these technologies are viable, Congress must find a way to monetize them for international sale.
