Why do energy efficiency

Freight can be moved more efficiently by improving the efficiency of rail and truck transportation and by shifting long-distance freight transport from trucks to rail. The four strategies above improve energy efficiency primarily through technology and design. However, the way people use these technologies will significantly impact their effectiveness. How does driving behavior and unnecessary idling impact gas mileage?

How many people will use public transportation if there is a cultural stigma against it?

In fact, the financial benefits of energy-efficient buildings yield a benefit-cost ratio of over 4 to 1, and 75 percent of those benefits can be attributed to health advantages. Energy efficiency is a great way to reduce your carbon footprint. Homes were responsible for 19 percent of national greenhouse gas emissions in , and implementing energy efficiency measures in your home can significantly reduce your emissions contribution.

The typical household can reduce its energy use and by extension its greenhouse gas emissions by 25 to 30 percent by investing in more efficient energy consumption. Energy expenses are often thought of as a fixed cost of owning a home or business, with reductions only possible through pricey renovations.

However, you can easily reduce your utility bills through simple energy conservation behaviors or small energy efficient purchases.

Programmable thermostats, advanced power strips, and energy efficient lighting can decrease your energy expenses with almost no effort on your part. Energy efficiency measures, no matter how small, are capable of generating utility savings over their service lives.

However, your savings are usually proportionate to the cost of the energy efficient upgrade — replacing light bulbs will only cost a few dollars, but will deliver marginal savings, while upgrading your attic insulation can save hundreds of dollars in heating and cooling bills.

Upgrades can range from simply plugging in a smart power strips to an HVAC system overhaul. How little or how much you choose to invest in energy efficiency is completely up to you. Utility residential electricity rates fluctuate seasonally and annually, but have risen steadily in the last decade. This trend is likely to continue into the future. In addition to cutting your monthly electricity bills now, conducting energy efficiency improvements on your home helps to insulate you from the financial impact of unpredictable sharp energy price increases that could happen in the years to come.

Electric utilities across the country offer energy efficiency programs to help homeowners and businesses reduce their energy use. No demolition required. A few small tweaks to each room could dramatically shrink your carbon footprint. Residents of the southern city spend twice as much as the average American on power. The prospect of geoengineering freaks us out.

And it should—it signifies the lateness of our climate hour. We will keep you informed with the latest alerts and progress reports.
