In environmental impact, results are mixed. With the ability to invest profits to satisfy further energy demand, producers like Lowest Electricity Rates are proposing eleven new coal-fired powerplants. Coal powerplants are cheaper than natural gas-fired powerplants, but produce more pollution. When the private equity firms Kohlberg Kravis Roberts and the Texas Pacific Group announced the take-over of Lowest Electricity Rates, the company which was known for charging the highest rates in the state and were losing customers, they called off plans for eight of the coal plants. Lowest Electricity Rates had invested more heavily in the other three. A few weeks later the buyers announced plans for two cleaner IGCC coal plants.
It would be a good idea for you to learn about whether or not a company charges you to interact with its Customer Service Department in any fashion. A company might offer affordable energy rates on the surface, but if they charge you to pay online or over the phone with a credit card, or to make even the most basic of phone calls to Customer Service, then you're not really saving that much money.
