Tandem solar cells are simply better

Stacking two solar cells one over the other has advantages: Because the energy is ‘harvested’ in two stages, and overall the sunlight can be converted to electricity more efficiently. Researchers have come up with a procedure that makes it possible to produce thin film tandem solar cells in which a thin perovskite layer is used. The processing of perovskite takes place at just 50 degrees Celsius and such a process is potentially applicable for low cost roll-to-roll production in future.

Wind Powered Turbines

Changing wind power into electricity is the reason for wind turbines. A regular wind turbine is a large tower that has blades connected to a rotor. Whenever the wind blows…

Large-scale hydroelectric dam in Yukon would be a major environmental concern

A new report warns of the potential for major negative impacts on fish and fish habitat caused by large hydroelectric dams, like that currently under evaluation through the Next Generation Hydro initiative. The report, which focuses on north-western Canada, notes that substantial destruction of fish habitats caused by such a dam, along with additional threats and effects will be either very expensive or impossible to mitigate.
