The focus on renewable energy sources is out of doubt one of factors that will define our future.
Climate Change, Global Warming, Kyoto Protocol, are just some of the terms recently entered in our vocabulary, but they will most probably last for a very long time. And our world's leaders have identified renewable energies as THE way forward to give next generations a liveable planet Earth. Hence Governmental support, hence an ever growing stream in the Renewable Energy Sector, hence the constant growth of figures of solar, wind, hydro power installations worldwide.
Both industrialised and developing countries' governments are launching normative instruments in order to stimulate the adoption of renewable energy sources. Incentives on feed-in tariffs, minimum 'clean generation' targets at national and supranational level (such as the March 2007 European Union Resolution which fixes at 20% the target of energy produced by renewable sources means in EU countries within the year 2020); fiscal exemptions or deductions for investments in renewable energy; emissions of green certificates negotiable on the global markets; 'net metering' systems; and the list could continue further more. Moreover, South African energy regulator, NERSA, has recently made a move in the same direction, updating and increasing feed-in tariffs for private renewable energies installations, with the REFIT Guidelines 2009.
