Germany could have reached Kyoto protocol obligations earlier if German solar investments would be relocated to Sicily. Additional benefits of emission savings and energy production should rise up to 72%. Nevertheless German solar power plants 2008 counted for 20 % of the financial benefits...

Germany could have reached obligations set by the Kyoto protocol earlier if German solar investments had been relocated to Sicily. Under the protocol, additional benefits of emission savings and energy production should rise to 72%. However in 2008, German solar power plants only accounted for...

Solar cells are a promising renewable, carbon-free electric energy resource to address the fossil fuel shortage and global warming. Energy conversion efficiencies around 40% have been recently achieved in laboratories using III-V semiconductor compounds as photovoltaic materials. This article...

Organic solar cells show great promise as an economically and environmentally friendly technology to utilize solar energy because of their simple fabrication processes and minimal material usage. However, new innovations and breakthroughs are needed for organic solar cell technology to become...

Silicon-based solar cells (SCs) promise to be an alternative energy source mainly due to: (1) a high efficiency-to-cost ratio, (2) the absence of environmental-degradation issues, and (3) great reliability. Transition from wafer-based to thin-film SC significantly reduces the cost of SCs,...

I have stated in my recent review article that no direct observation of multiple exciton generation (MEG) in the shape of photocurrent extracted from a semiconductor had been made yet. [...]

Biofuels are increasingly regarded as energy sources with the potential to solve diverse problems related to serious concerns, including climate change, environmental degradation, energy supply, and energy security. Here we examine biofuels, primarily biofuels used for transportation (e.g.,...

The unprecedented deterioration of our global environment has increased the necessity of relying upon Green Economic policies as critical and effective environmental management tools. The current situation has stimulated extensive research and debate among global interest groups. This has...

Considering that the major part of greenhouse gases is carbon dioxide, there is a global concern aimed at reducing carbon emissions. Additionally, major consumer countries are looking for alternative sources of energy to avoid the impact of higher fossil fuel prices and political instability in...
