Not to rain on your parade, but programs like this from big power companies are essentially meant to allow customers to feel good while simultaneously not going through the work and cost of switching completely to renewable power. That's because the power companies want to keep people from developing competition to them... if enough individuals install solar plants with battery storage, eventually they power company simply won't be needed any more, which is what they're trying to avoid. By selling "green" feel good power, they quiet the impulse that people like you get to make changes that would impact their business. It's still good that you choose to purchase green power over e.g. coal fired power, but it's also the power companies you're keeping in business that are causing a lot of climate change, and who have contributed to it all along.
