Wind energy has become low cost option in United States

Renewable energy sources such as solar and wind are declining in prices. This especially refers to latter as according to the US Department of Energy report wind energy prices have gone below 2.5c/kWh in 2014, which is a 65.5{f24b02adee2102ff0c5f5079c50862fc8ba5fa53f8615b567037555463da2377} decline compared to 2009.There are many utilities which are now selecting wind as one of the cheapest renewable energy options, particularly in the central United States. This means that wind energy is now cost-competitive and economically viable option that can compete with coal and natural gas in many U.S. states.The strong growth of wind energy sector in United States does not only mean more clean renewable energy and less fossil fuels burned, it also means plenty jobs for U.S. economy. It has been estimated …

‘Greener’ way to assemble materials for solar applications

The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair. Today, formation of that polymer assembly requires solvents that can harm the environment, but scientists have found a ‘greener’ way to control the assembly of photovoltaic polymers in water using a surfactant — a detergent-like molecule — as a template.

Super environmentally friendly: the ‘fool’s gold battery’

High-performance lithium ion batteries face a major problem: Lithium will eventually start to run out as batteries are deployed in electric cars and stationary storage units. Researchers have now discovered an alternative: the “fool’s gold battery”. It consists of iron, sulfur, sodium and magnesium – all elements that are in plentiful supply. This means that giant storage batteries could be built on the cheap and used stationary in buildings or next to power plants, for instance.

Wave energy integration costs should compare favorably to other energy sources

A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power.
