Affordable, renewable energy

Choosing renewable energy in Texas is getting easier and cheaper. We'll be providing our members with 100% renewable electricity, generated from solar and wind.

We invest in technology to help keep our costs low. And we only partner with companies that do the same. So we pass the savings straight on to our members.

And it all comes without an annual contract.

One low rate for all

We make energy simpler, so we have just one plan. That way, you know you're always on our best possible price. Our price reflects the true cost of energy, so when wholesale energy costs move, so does our rate. If they go up, we work hard to limit increases to our members and always give advance notice. And if they go down, we quickly pass those savings on to you.

This isn't our first rodeo

Bulb is the UK's fastest growing renewable energy supplier, bringing energy to over a million homes and businesses.

Collectively, the Bulb Community is saving 5.4 million tons of CO2 from entering the atmosphere every year. And we're the #1 rated energy supplier in the UK for service. Next stop, Texas.
