This light-control film is based on the fact that there is a change in the incident angle of sunlight between summer and winter. The film blocks sunlight in summer by using total reflection but transmits it in winter. Unlike other light-control films, the film can control the transmission of direct sunlight while always allowing people inside to see the view outside the window.
The purpose of this report by Bloomberg New Energy Finance, sponsored by Swiss Re, is to assess the underlying trends in the renewable energy sector and consider how new risk management and insurance products can contribute to the sector's growth and long-term sustainability.
Engineers at the University of California, Berkeley, have developed an inexpensive new way to grow thin films of a material prized in the semiconductor and photovoltaic industries, an achievement that could bring high-end solar cells within reach of consumer pocketbooks.
Could there come a time in which the carbon dioxide emitted from natural gas or coal-burning power plants that warms the atmosphere and exacerbates global climate change is harvested and used to produce clean, green and renewable liquid transportation fuels? A pathway to that possibility has been opened by a team of researchers who have engineered a microbe now being used to produce biodegradable plastic into a strain that can produce a high-performance advanced biofuel.
Although recommended in the Coalition's Direct Action Plan and the Carbon Farming Initiative, offsetting greenhouse gas emissions by increasing carbon storage in Australian agricultural soils is not likely to be effective, say experts from the University of Melbourne.
Researchers have called for a system of carbon emission assessments that reflect better the true contribution of each emitting nation to the increase in atmospheric CO2 and promote preservation of forests, particularly in tropical regions.
