One of the most productive, and potentially lucrative, ways to reduce greenhouse gas emissions is through improving the efficiency of energy and transportation infrastructure. If we use lighting as an example, a standard incandescent light bulb is only 4% efficient. This means that you only get to use 4% of the energy that you pay for, which largely comes from burning fossil fuels. By comparison, compact fluorescent lighting is 10-15 times more efficient, while producing the same amount of light. There are multiple opportunities for increasing energy and transportation efficiency which can dramatically reduce costs, help meet mandated carbon reduction goals, and reduce the climate change impact, all at the same time.
