Increasing your water heater temperature by just 10ÂºF from 130ÂºF to 140ÂºF may increase heat loss resulting in a larger electric bill from $30 to $75 dollars annually. Setting the temperature to 140ÂºF can also increase demand losses resulting in an annual expense of up to $500 dollars.

New material can store solar energy to warm you up later. A solid film releases a burst of heat just when you need it. Solar projects are usually focused on generating electricity, but we could arguably save more power by storing heat. Scientists from MIT have created a new type of solid material that does exactly that. When exposed to sunlight, it assumes a charged state that can be maintained for long periods of time.
