Green Options

Fourty percent or more of the Amazon rainforest will be “decimated” by the middle of the next century even if we cut all CO2 emissions by 2050, said the UK Met Office. The finding was presented this past month in Copenhagen, which is preparing to host the UN Climate Change Conference in December.

In this satellite image of deforestation in Brazil, tropical rainforest appears bright red, while pale red and brown areas represent cleared land. Black and gray areas have probably been recently burned.

Green plants, trees and their leaves remove noxious carbon dioxide from the air during a process known as Photosynthesis. This is why we are all so upset about the ruination of the rain forests, which act as natural air cleaners in volume due to the density of vegetation.

Researchers at Massachusetts Institute of Technology (MIT) have discovered a new way of storing energy from sunlight that could lead to ‘unlimited’ solar power.

The process, loosely based on plant photosynthesis, uses solar energy to split water into hydrogen and oxygen gases. When needed, the gases can then be re-combined in a fuel cell, creating carbon-free electricity whether the sun is shining or not.

According to project leader Prof. Daniel Nocera, “This is the nirvana of what we’ve been talking about for years. Solar power has always been a limited, far-off solution. Now, we can seriously think about solar power as unlimited and soon.”
