Wind power is cheaper than electricity from gas

For a long time, people have no doubt about this alternative energy source but the cost of 'green energy' is still more expensive than petroleum. Until now .

Last week, at the Brazilian National Energy Department (Aneel), there was a bidding. When signing the contract, there were 78 wind energy projects participating, with a total capacity of 1928 MW, the unit price of about 99.5 USD / MWh. Thus, wind energy has a lower price than its average price in the previous year. In addition, it is cheaper than electricity from natural gas, currently priced at 103 USD / MWh in Brazil.

The wind energy cost reduction will change the world energy balance.

In 2010 in Germany, the country is leading the world in wind power, with the total renewable energy generated exceeding energy from oil and gas combined. But the price of wind power is still more expensive than energy from petroleum and nuclear power.

Investing in renewable energy sources in the world is growing very fast. According to the United Nations, in 2010 the total investment in this sector increased by 32% over the previous year. up to 211 billion USD. Among renewable energy, wind power accounts for the highest proportion with an investment of 94.7USD, 30% higher than 2009. The lowering of the cost of energy balance inclines to this industry. In the past year alone, the cost of wind power decreased by 18%.

The biggest investor in renewable electricity is China, with a capital of 50 billion USD, of which 50% is for wind power.

Compared to 2009, investment in renewable energy increased by 28%. In Brazil, total wind power capacity doubled in 2009-2010. With new projects, the country will bring renewable energy to 45.4% in the energy structure.

Compared to other members of the BRIC (Brazil, Russia, India, China), Russia's renewable energy problem remains stagnant. Thanks to abundant gas resources, Russia has not paid adequate attention to green energy. Especially in the European part of Russia, about 60% of energy goes from gas and 23% from nuclear power.

Meanwhile, the potential for wind resources in Russia is huge, estimated at 260 billion kWh per year, equal to 30% of the current domestic electricity production.
