As the third-largest coal-producing state in the nation, a sizable portion of everyone’s electricity comes from coal, regardless of the plan type you choose. But times are changing: Pennsylvania's Alternative Energy Portfolio Standard requires that 18 percent of all electricity sold by 2021 be sourced from renewable energy. The state subsidizes the increase of renewable energy, and by opting for a green plan, your electricity payments do the same.

The nature and state of market reform of the electricity market often determines whether electric companies are able to be involved in just some of these processes without having to own the entire infrastructure, or citizens choose which components of infrastructure to patronise. In countries where electricity provision is deregulated, end-users of electricity may opt for more costly green electricity.
As an Exelon company, Constellation Energy is part of one of the biggest — and historically most polluting — corporations in North America. Given Exelon’s vast production energy, ranking on the PERI Toxic 100 list is perhaps not that surprising. The good news is that Exelon is upfront about its room for eco-friendly improvement and make it easy for Constellation customers to go green, too.
The electric power industry covers the generation, transmission, distribution and sale of electric power to the general public and industry. The commercial distribution of electric power started in 1882 when electricity was produced for electric lighting. In the 1880s and 1890s, growing economic and safety concerns lead to the regulation of the industry. Once an expensive novelty limited to the most densely populated areas, reliable and economical electric power has become an essential aspect for normal operation of all elements of developed economies.
