Affordable, renewable energy

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

We keep costs low by investing in technology and working with companies that do the same. All of this creates savings that go straight to you.

And it all comes without an annual contract.

One fair rate for all

We have just one plan, so you're always getting the best possible price. If wholesale 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.

See for yourself

We’re 23% cheaper than the other guys. In fact, send your last energy bill to [email protected] and we’ll show you how much you can lower your bill. It’s usually hundreds of dollars.

This isn't our first rodeo
