use of RE sources. All RE sources combined accounted for only 17.6% share of electricity production in the world, with hydroelectric power providing almost 90% of it. All other RE sources provided only 1.7% of electricity in the world. However, the RE technologies of wind power and solar energy have vastly improved in the last two decades and are becoming more cost effective. As these technologies mature and become even more cost competitive in the future they may be in a position to replace a major fraction of fossil fuels for electricity generation. Therefore, substituting fossil fuels with RE for electricity generation must be an important part of any strategy of reducing CO2 emissions into the atmosphere and combating global climate change.
