Global climate change challenges us to transform the ways in which we generate and use energy. Based on the findings of the world’s climate scientists and mitigation experts, substantial emissions reductions are necessary to avoid significant changes in the earth’s atmosphere with severe consequences for human health and the global environment. The most recent consensus findings of the Intergovernmental Panel on Climate Change (IPCC) state that greenhouse gas (GHG) emissions need to be reduced by 50 to 85 percent by 2050 to avoid global temperature rise of 2.5 degrees Celsius or more, and global GHG emissions must stop rising no later than 2015 (IPCC, 2007). With the majority of government leaders taking steps to act on these findings, there are intensified efforts in many nations to develop low-cost emissions reduction options in the near term. This puts energy efficiency in the climate policy spotlight as a near-term, low-cost resource for reducing the growth in carbon emissions and lowering the ultimate cost of reducing GHG emissions. Energy efficiency provides multiple public benefits regardless of its carbon emissions impacts. It reduces home and business energy costs, improves productivity, stimulates economic growth, reduces energy market prices, improves energy system reliability, reduces criteria air pollutant emissions, and enhances national energy security. Savings from reduced energy consumption typically outweigh the cost of the energy efficiency investment. Thus, efficiency reduces the overall cost of energy services.

Increased energy efficiency investment combats global climate change in two primary ways. First, simply put, “the less energy used, the fewer emissions produced.” While this general statement overlooks the more complex relationships between energy efficiency and carbon dioxide (CO2) emissions, it places energy efficiency in a core role for future energy and climate policies and programs. Second, cost-effective energy efficiency achieves these environmental benefits at low cost, and thus can reduce the economic costs of achieving climate policy goals.
The remaining parts I am going to post soon.There are lots of thing remaining here to write.I will become always fresh when writing in such topics.
