In Houston, 0% of people have switched to a plan that has some renewable energy component to it. Another 0% have switched to a plan that is partially renewable, while 0% have switched to a plan that powers homes completely by renewable electricity. This of course means that 100% of people have remained on a plan powered by traditional sources of electricity such as coal or nuclear power.
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.

Price, of course. Prices are expressed in cents/kilowatt hour. Plan types include fixed rates and variable rates. Fixed rates offer consistency throughout the plan term, which can run from six to 36 months. Variable rates can change monthly - they're great when prices go down, but not-so-great when they don't. Finally, if you care about your carbon footprint, you may choose a plan sourced by solar or wind energy.

Keeping on top:  With deregulation, a whole host of electric resellers jumped into the market because there’s a whole lot of electricity to sell:  if Texas were a country, it’d be the 11th largest electricity consumer in the world!  Just by itself, it uses as much electricity as Spain or Great Britain!  That means there’s a whole lot of information you have to find, absorb, and process to make sure you’re getting the best rate for your needs.

No deposit electricity plans also offer a subjective advantages. Thanks to smart meters, electricity providers can offer you smartphone apps that send notifications when your balance is getting low, so you can purchase more kilowatt-hours before your account drops to zero. However, this also means you will track your energy consumption more frequently, as opposed to only once per billing period. Energy consumers who monitor their kilowatt-hour usage tend to consume less energy that those who only wait for power bills once per billing period.


Anyone on a standard rate tariff is at risk of seeing rising energy bills – so one of the best ways to protect from energy price increases is to switch to a fixed rate tariff. This means that for the duration of the deal, the cost of your energy and gas will be fixed. You may be able to switch to a cheaper fixed price tariff at any point, or you may have to pay a fee if you switch before the end of the deal – so check your paperwork.
Knowing how much electricity you use each month is important to finding the cheapest electricity plan. For Houstonians, usage is typically the lowest in the winter and highest in the summer.

To avoid electric bill surprises during the peak summer months, you’ll need to accurately know your peak electricity usage which typically occurs in August.
