Affordable, renewable energy

Choosing renewable energy in Texas is now easier and cheaper. At Bulb, we use wind and solar to supply our members with 100% green energy that costs less and keeps Texas clean.

And it all comes with no annual contracts and no exit fees.

One fair plan for all

We have just one plan, so you're always getting the best possible price. If energy costs go up, we work hard to limit the increase to our members. And if they go down, we hand those savings back to you. We like to keep things simple around here—no tiers, no tricks.

With that in mind, you should know we’ll be freezing our rate this summer, which means your energy price won’t budge from June 1 to August 31.
