In deregulated states, electricity providers simply can't do business like that because consumers like you are demanding energy from renewable sources. Threats of global warming are too terrible to be irresponsible with our energy sources anymore. As a result, each electric company is pushing forward to find renewable energy sources that are cheaper, cleaner, and more reliable than older forms of energy.
Every single energy supplier in the UK is regulated by Ofgem, the industry regulator. This means that the smaller, lesser-known companies have to follow exactly the same rules as the bigger, more established ones. If a company goes bust, you’ll be covered by Ofgem – they’ll ensure your supply isn’t cut off, and they’ll appoint a new supplier to take over your tariff.

Most of Direct Energy’s plans allow you to earn Plenti points — you get 1,000 as soon as you sign up. That initial windfall is about as good as it gets. You keep accumulating rewards with every payment, but just one point for every dollar you spend on supply charges (what you pay to Direct Energy vs. your EDC — so about two-thirds of your total bill). A Plenti point equates to about one cent, so that 1,000 point bonus works out to $10 when you cash it in with a Plenti merchant (Rite Aid, Macy’s, etc.) You’d have to spend a further $1,000 in supply charges before making off with another $10.00 in Plenti points.
1. Contracts: Before, there were no contracts. You signed up or you didn’t. When it’s the only game in town, you have to play by their rules. Nowadays, you’ll see these ultra-fabulous rates bandied about but it’s only by carefully scrutinizing the fine print that you’ll discover those wonderful rates come with a one-year lock-down or other catches.
