Saving energy is saving money on your electricity bill, and is increasingly popular in the 21st century. Installing an air circulating fan can help and you will get a $50 tax credit for doing so. Energy efficient light bulbs are also popular, lasting ten times longer than regular bulbs. Showerheads with reduced water pressure cost lest than $10 and using the air dry setting, rather the heat dry, on your dishwasher will also save you power and money.
