Renewable energy is a continually renewable energy environment that includes solar energy, wind power, hydropower, biomass energy, sea turbidity, emissions, and geothermal energy. From 2005 to 2006, 18% of the world’s total energy produced from renewable energy. The remaining 13% are from traditional fuels, 3% from water (15% of the world’s electricity), 1.3% from solar energy (solar heating), and about 0.8% is powered by geothermal, wind, solar and ocean energy.
Global warming and rising oil prices are the main cause of extensive research on renewable energy, investing, production and use in research. Investment in this area has increased from $ 80 billion in 2005 to $ 2344 billion in 2006
Wind power consumption increased by 30% annually, with a total installed wind power capacity of 100 GW (GW). Wind power is widely used in European and American countries. The installed capacity of photovoltaic panels for solar energy power plants has surpassed 2,000 Megawatts in 2006 and is most commonly used in Germany and Spain. The solar thermal power plant is widely used in the United States and Spain, the largest of which is the Ivanpapa solar thermal power plant in the Mojave of California, USA. The installed capacity of the plant will be 377 MW. The world’s largest geothermal power plant is the Geyser station in California, USA, with a capacity of 750 MW. Brazil is the world’s largest producer of sugar cane from sugar cane, which supplies 18% of its fuel to ethanol. It is also widely used in the United States.
Besides, projects for remote cities are being implemented with renewable energy projects. Kenya is considered the world’s most widely used small-scale renewable energy source. In the country, about 30,000 solar photovoltaic generators are sold for 20-100 W / year.
