Economic Energy

May 6th, 2016

We began to assess the feasibility of such a change and take one even greater challenge: determine how 100 percent of the energy consumed around the world, to all intents and purposes, could be supplied by wind, water and sunlight, and as soon as in 2030. Our plan is presented here. Scientists have been accumulating pieces until the present moment so in less than a decade, analyzing different pieces of the challenge, you can reach is 100% renewable target. More recently, in 2009, a study by Stanford University ranked energy systems according to their impacts on global warming, pollution, water supply, use of land, wildlife and other problems. The best choices were, in this order, wind, solar, geothermal, tidal and hydroelectric power all which are driven by wind, water or light from the Sun (known with acronym WWS in English).Nuclear, coal with CO2 capture and ethanol were options worse, as well as oil and natural gas. The study also found that electric vehicles with batteries and hydrogen fuel, could largely eliminate pollution in the transport sector.Our plan needs millions of wind turbines, hydroelectric and solar installations, much as solar photovoltaic.

The numbers are large, but the scale is not an insurmountable obstacle; our society has previously already achieved massive transformations. During the second world war, the United States retooled automobile factories to produce 300,000 aircraft and other countries produced 486,000 more aircraft. In 1956, United States began the creation of the State Highway system, that 35 years later spread to 47,000 miles, changing trade and society. it is possible to transform the world’s energy systems? Could it be made in two decades? The answers depend on the chosen technologies, the availability of critical materials and factors Economic and political. Only clean renewable energy technologies have seductive sources: wind, which also produces waves; water, which includes hydropower, tidal and geothermal energy (water heated by hot rocks); Sun, which includes photovoltaic and thermoelectric solar that focus the sunlight to heat a fluid that drives a turbine to generate electricity.
