Energy legislation could bring deep change

It all costs.

Investors would see a new line item on companies financial reports: the cost of carbon permits.

Some increases would be reflected in the prices of goods and services, economics say. It might mean shelling out more for a toy because plastic, a petroleum-based product, is more expensive, or paying more for a house because of new efficiency requirements.

Homes and businesses could use less energy
Not all the higher energy costs would show up in people's utility bills. Households, as well as business and factories — including those, for example, making plastic for toys — could use less energy, or at least use it more efficiently. The poorest of homes could get a government check as a rebate for high energy costs. That money would come from selling pollution allowances for industry.

Energy experts in government and industry say a price on carbon pollution would lead to new ways to make renewable energy less expensive, while emphasizing how people can use it more wisely.

Potential changes to how homes are built and even financed seem likely as energy efficiency is taken into account in building codes and the cost of mortgages. With the cost of energy increasing, homeowners and businesses would have greater incentive to use more energy-efficient lighting, windows and insulation.

But don't think that the traditional sources of energy would disappear.

Coal probably still king
Coal, which today accounts for half the electricity produced, would continue as a major energy source, though a less polluting one, energy experts forecast. That would mean capturing the carbon released when coal is burned.

It's a technological hurdle with a complication: "not in my back yard" complaints over what to do with the billions of tons of carbon dioxide captured from power plants and pumped beneath the earth. Would people feel comfortable having it stored near or under their homes, factories and businesses?

Scientists studying climate change say carbon capture from power plants is essential if the country is to take up the challenge against global warming.

The cleaner energy economy also put nuclear energy front and center. Does the U.S. build new power plants? If so, where, and where does all the waste go? Nuclear energy makes up about one-fifth of the nation's electricity today.

The House-passed bill contains provisions to make it easier to get loan guarantees and expands the nuclear industry's access to loans for reactor construction. An Environmental Protection Agency analysis that shows modest future costs from a low-climate energy world assumes a significant expansion of nuclear energy. The Senate could add more incentives for the nuclear industry.

The new energy world would rely more on natural gas. This abundant fossil fuel emits carbon but is relatively clean when compared with coal. But people would have to decide whether to accept new pipelines that are needed to ship the gas around the country — just as they would have to deal with the need for new power lines to move solar and wind energy to where it's needed.
