Once you create a government bureaucracy, it doesn't matter who is in congress, senate, etc. They grow, they must justify their existance or get money cut, etc, etc. EPA was originally created to help monitor environmental concerns and offer environmental solutions to environmental problems. It has become a monster, creating tons of useless paperwork for private companies to fill out to do work they have been doing for 150 years. My company was being environmental friendly before the EPA paperwork, fees, and inspections. We wanted to satisfy our CUSTOMERS. We cleaned up our projects, we didn't allow run off water and mud. Didn't need some nanny government bureaucracy telling us what to do. As a mater of fact, they adoped our standards and applied them nationwide. Now we have to pay and get a permit to do what we have always have done. Stupid and costly.
Same with insurance, government gets involved telling insurance companies what they can and can't do causes everyones insurance to go up.
Government bureaucracies have NEVER solved ANY problems only created them. Laws, insurance companies, and lawsuits would have easily solved problems without government agencies.
As a mater of fact, industrial accidents were going down before OSHA. After OSHA was created, industrial accidents went up. Why were they going down? Lawsuits and insurance companies were making workplaces safer. Didn't need OSHA.
Has the Energy department got us away from imported oil that it was originally created to do? Nope. Only made building and maintaining various types of electrical production more costly.
Private industry will find the solutions to problems if you let them and it is cost effective. Alternative energy will come on line as the cost to build, operate or produce it gets lower than conventional energy sources.
Kerosene replaced whale oil, because whales were being hunted to extinction. Gasoline replaced alcohol because it was cheap and easier to get and you didn't have to make it. Diesel replaced coal for trains and ships because it was cheaper and easier to handle. Coal replaced wood, because wood wasn't always available for steam engines like in the plains states, deserts, mountains, and on the sea. Never took the government to interfere and force one way or another.
Alternatives are now available, but will require some effort to change the infrastructure and it has to be cost effective. Natural gas and diesel will eventually replace gasoline. Later, in 100 or 200 years, the natural gas distribution system will probably be hydrogen.
