Crystalline perovskite cells are the key to cutting-edge thin-film solar cells. Although they already achieve very high levels of efficiency in the laboratory, commercial applications are hampered by the fact that the material is still too unstable. Furthermore, there is no reliable industrial production process for perovskites.
The world’s leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C, beyond which even half a degree will significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people.
In June 1979 President Jimmy Carter made a huge investment by installing 32 solar panels on the White House roof. At the time, the price of photovoltaic cells hovered close to $40/watt. Seven years later Regan took the panels off again, and when President Obama put the White House back on the solar track just a few months ago, the price of solar PV cells had dropped to $0.74/watt.
Cogeneration is also called as combined heat and power or combine heat and power. As it name indicates cogeneration works on concept of producing two different form of energy by using one single source of fuel. Out of these two forms one must be heat or thermal energy and other one is either electrical or mechanical energy.
It’s global warming that will hurt the economy in red states, not a carbon tax.
Geothermal energy is currently believed to be one of the most advantageous sources of energy. Not only is it a renewable type of energy but is also present in most areas, outperforming even some conventional sources in many aspects.
America’s technology corporate giants have led the corporate renewables procurement trend, but two of the biggest names in tech just reached a new mark: Apple and Google are now both 100% powered by renewable energy.
Stuttgart’s location in a valley basin, its mild climate, low wind speeds, industrial activity and high volume of traffic has made it susceptible to poor air quality. Development on the valley slopes has prevented air from moving through the city, which worsens the air quality and contributes to the urban heat island effect.
Falling costs, Chinese dominance and competition in battery technology are some of the main developments to monitor in 2018.
A review of all the headlines published by Renewable Energy World this year revealed many interesting trends in the global renewable energy marketplace. Ten trends, however, stand out as being major stories to watch in 2017.
