Tour the Country’s Energy Infrastructure Through A New Interactive Map

Tour the Country’s Energy Infrastructure Through A New Interactive Map | Développement durable et efficacité énergétique | Scoop.it

Examining the network of power plants, transmission wires, and pipelines gives new insights into the inner workings of the electrical grid.


Every time you switch on a light, charge your electronics or heat your home in the winter, you’re relying upon a tremendous network of energy infrastructure that literally stretches across the country: power plants, pipelines, transmission wires and storage facilities.

It can be hard to visualize all this infrastructure and understand how it makes abundant energy available throughout the country. To help see a bigger picture, a new map, just released by the U.S. Energy Information Administration, combines a range of data (locations of power plants, electricity lines, natural gas pipelines, refineries, storage facilities and more) into an elegant, interactive interface that helps to piece how it all fits together. You can also zoom in on your own city to see the types of power plants generating electricity nearby.

The map also includes layers of real-time information on storm movement and risks, allowing energy analysts to better understand the potential impact of storms.

Why should utilities promote energy efficiency?

Why should utilities promote energy efficiency? | Développement durable et efficacité énergétique | Scoop.it

He acknowledged that there was “an inherent perverse disincentive for utility suppliers to support energy efficiency, since their earnings expand along with increased utilities usage”. Hence, there is a need for suppliers to receive incentives so they could, for instance “take the lead and help an industrial customer retrofit their building to be more energy-efficient, in locations where the customer lacks expertise to do so or faces competing demands for its capital”.

Solar expected to make up 40 percent of PG&E's renewable portfolio by 2020

Solar expected to make up 40 percent of PG&E's renewable portfolio by 2020 | Développement durable et efficacité énergétique | Scoop.it
Solar power, which makes up a tiny part of Californias overall energy mix, will account for the biggest piece of the states renewable energy pie by the end of the decade, according to the states largest utilities.

Last year, Pacific Gas & Electric got most of its renewable energy from wind, bioenergy, geothermal and small hydropower dams. Solar accounted for about 1 percent. But that mix is quickly changing, and by 2020, the San Francisco-based utility expects solar to account for 40 percent of its renewable portfolio.
California's aggressive "Renewable Portfolio Standard" law requires utilities to purchase 33 percent of their electricity from renewable sources by 2020. Bioenergy, geothermal, solar, wind, wave and tidal power and small hydroelectric dams -- which cause less harm to the environment than large hydro dams -- all count toward meeting the law...
But solar is the fastest-growing piece of renewable portfolios, driven by federal stimulus funding for large solar power plants, a drop in solar panel prices and a boom in the number of developers competing for long-term utility contracts in California...

A New Way to Foot Efficiency Upgrades

A New Way to Foot Efficiency Upgrades | Développement durable et efficacité énergétique | Scoop.it
For commercial property owners in California looking to finance energy efficiency upgrades for their buildings, the process should be a bit easier and cheaper come early next year, thanks to a new pilot program approved last week by the state’s Public Utilities Commission.

Based on an “on-bill repayment” feature, the program would allow the property owner to avoid large upfront costs and instead pay for upgrades through regular installments on his utility bill. The idea is that the energy cost savings would cover or exceed the loan or the leasing repayment added to the bill each month. The repayment remains on the property’s utility bill until it’s paid off, even if the property changes ownership, and the utility would have the authority to cut off service for nonpayment.


The concept is not new. About a dozen states offer similar programs. California’s new twist is the source of financing and the obligation to repay the loan regardless of a change in ownership.

Cities Getting Local Energy Choice with Aggregation

Cities Getting Local Energy Choice with Aggregation | Développement durable et efficacité énergétique | Scoop.it

Over 200 Illinois towns helped cut their citizens' electric bills in 2012, and some even achieved 100% renewable energy, thanks to a state law that lets cities choose their electricity provider. The law, called community choice aggregation, lets municipalities pick from competitive electricity suppliers for their residential and small business customers, but without having to purchase and operate the local grid (as when becoming a municipal utility).

Nonprofit hopes to help small biz plug into energy efficiency

While programs to aid and encourage large firms to reduce their energy consumption have been popular and helped to keep electricity consumption in check over the last few years in the state, small businesses have had difficulty accessing the programs due to financial and time constraints, Wrice said.

"You can't keep doing the Pratt & Whitneys of the world," she said. "At some point, you have to target these smaller businesses. Otherwise you're going to have ... boarded up main streets."
