Whether different energy sources such as biofuels, hydrogen, solar, geothermal, or nuclear energy can meet energy demands better than finite fossil fuels such as oil and coal remains hotly debated.
Proponents of alternative energy argue that fossil fuels are inefficient, unsustainable, environmentally destructive, and the primary contributor to global climate change. They say renewable energies are a viable and immediately needed alternative to fossil fuel use that could boost the US economy and reduce reliance on foreign energy sources.
Opponents contend that many technological hurdles have to be overcome before alternative energy can replace even a small portion of the power provided by fossil fuels. They say that fossil fuels will last hundreds of years longer, be made increasingly efficient, remain the most economical choice, and that reliance on inefficient alternative energies will hurt the economy. The source of renewable energy has to be able to solar heat. First of all, put double efficiency hydro-thermal turbines on the market. I just invented them. Next, start producing methanol from hardwoods with the aid of the double efficiency hydro-thermal turbines. The process for manufacture of methanol should be mounted on mobile supports and placed in the forest, so that the carbon dioxide from the process will speed up the growth of trees.
