The more cool air you lose, the harder your air conditioning unit works and the higher your electricity bill will be. Install blinds, hang curtains or get storm windows made to keep cool air from seeping out. Even mesh screens, on the outside of your home, will help deflect solar radiation. You might even consider replacing old windows that leak cold air and let in heat.
Residents and business owners have been able to shop Texas electricity supply rates for more than a decade. When Texans gained the ability to choose their desired energy company in 2002, the electric industry divided into two parts: supply and delivery. Retail energy companies in Texas compete for business, offering a variety of term agreements and supply rates for consumers to choose from.

Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
