Peter Cennamo Trumatech's CEO discusses raw energy resources

The raw energy sources found to be the most promising are wind, concentrated solar (the use of mirrors to heat a fluid), geothermal, tidal, solar photovoltaics (rooftop solar panels), wave and hydroelectric.

Although we have been aware of the downsides of traditional energy sources for some time, the movement towards alternative and more renewable energy has been slow. There are a number of reasons for this, but the most powerful is pure economics. Cheap and plentiful oil and natural gas made it very difficult for other energy methods, such as solar, wind, geothermal, etc, to be economically competitive.

Newer more efficient technology will not only lower costs of wind, solar, geothermal, and other energy sources, they also will increase efficiency. More efficient systems make money by saving money. When there is less cost to create the same measure of energy, increasing global demand can be met.

Putting people to work building wind turbines, solar plants, geothermal plants, electric vehicles and transmission lines would not only create jobs but would also reduce costs due to health care, crop damage and climate damage from current vehicle and electric power pollution, as well as provide the world with a truly unlimited supply of clean power.
