Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization. New government spending, regulation and policies helped the industry weather the global financial crisis better than many other sectors. Scientists have advanced a plan to power 100% of the world's energy with wind, hydroelectric, and solar power by the year2030, recommending renewable energy subsidies and a price on carbon reflecting its cost for flood and related expenses.
Wind, water and solar power. using current technology can supply all of the world's energy by 2030, and has the advantage that consumption is reduced by 30%. Excess production would be used to produce hydrogen for use in ships and airplanes. It also has the advantage that it lasts for as long as we are on the planet, vs. less than a century for most of the non-renewable resources. An investment in non-renewable resources of $8 trillion is required to maintain current levels of production for 25 years, a cost that is avoided by transitioning instead to the renewables.
