This year’s election is about power — the power to shape the nation’s domestic and foreign priorities; the power to lead, to legislate, to govern. Energy policy, defining how we use energy to power our economy and our lives, is among the most pressing issues for the next four years.

There is no easy answer to what is the best source of energy or electricity. Is the priority reliability, affordability, the economy, international human rights, limiting greenhouse gas emissions, preserving environmental resources, or human health?

In the early days of electricity, energy systems were small and localized. The Pearl Street Station in New York City, launched in 1882, was the first of these complete systems, connecting a 100-volt generator that burned coal to power a few hundred lamps in the neighborhood. Soon, many similar self-contained, isolated systems were built across the country.

The electricity industry has three main components: the power plants, the transmission lines, and the distribution to you through utilities. Mostly, three different entities operate these components. A power company owns a plant, some non-profit transmission company is responsible for the transmission, and a utility distributes the electricity to users.

Often called “emission trading”, in a working cap-and-trade system, industries that release undesirable compounds into the air, water, or soil have limits of how much they can emit based upon pollution permits. Depending on the system, polluters either are given or have to buy their permits. The government establishes how much total pollution that the permits will grant, an umbrella cap on the economy. If an industry participant wants to release more than the permit allows, they buy the right from another industry player, if available, or perhaps face penalties, depending on the details.
