It’s Easy Being Green: A Guide to Renewable Energy and Efficiency

There is a lot of discussion centered around non-fossil-fuel energy sources and energy efficiency right now. With atmospheric concentrations of CO2 rising to damaging levels, renewable energy might be the best option for reversing the effects of global warning and reliance on fossil fuels. But how does one know how to choose an alternative energy source? (more…)

Abgelegt in global warming

Only in the last 50 years have scientists recognized the link between global warming and carbon dioxide, CO2 for short. Carbon dioxide, along with methane, water vapor, and some other gases care called greenhouse gases, because they have the effect of trapping in heat on the Earth like a greenhouse. In a greenhouse, glass panels allow the heat and light of the sun to enter, but prevent them from escaping, boosting the temperature inside, allowing plants to grow year round despite the conditions outdoors. Similarly, greenhouse gases trap heat from the sun. (more…)
