Plant Closure Opportunity: Hitting Those Clean Energy Notes

March 28, 2015 by EDF Energy Exchange
1

Plant Closure and Green Policies

It may seem logical that once a power plant closes, another one needs to be built to replace it – after all, we need to make up for its potential energy generation with more natural gas or nuclear-powered energy, right? Maybe, but plant closures are also an opportunity for clean energy.[read more]

New Kind of "Tandem" Solar Cell Developed

March 28, 2015 by Energy @ MIT

Solar Cell Invention

Researchers have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun’s energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations.[read more]

Reducing Stress on India's Grid With Efficient, Climate-Friendly Air Conditioning Refrigerants

March 27, 2015 by NRDC Switchboard

India Energy Consumption Efficiency

India leapfrogging over antiquated, soon-to-be obsolete, and inefficient refrigerants will benefit the power sector while saving consumers money. It will also advance the Indian economy, ensure Indian industries can compete in the international market, and help mitigate climate change.[read more]

ComEd Backs a Bill to Impose Demand Charges on Residential Customers

March 27, 2015 by Katherine Tweed

The Illinois General Assembly introduced legislation recently that would allow ComEd to invest more than $400 million in projects like community solar, along with grid-edge assets such as microgrids and public electric-vehicle charging infrastructure.[read more]

Emerging Technologies Can Pave the Way for Time-Variant Electricity Pricing

March 27, 2015 by EDF Energy Exchange

Variable Electricity Pricing and Tech

The amount of energy we use at any given time is constantly changing. Lights are switched on and off by time of day, appliances operate based on the season. In order to meet our dynamic energy demands, our system has to have the infrastructure and resources in place to respond when needed.[read more]

The Secret to Cost Effective Energy Storage

March 27, 2015 by Nigel Morris

I am as optimistic as anyone about energy storage and try as I may I can’t (in my own head) separate the growth in electric vehicle sales and the inevitable flood of lower cost energy storage for stationary applications. There are deep and close connections that will flow both ways.[read more]

U.S. Electricity Rates Are Jumping - Or Are They?

Electricity Rate Analysis

Despite the volatility in wholesale markets, and the billions of dollars in upgrades to the electricity grid, the price most homeowners pay for energy is likely going to stay relatively flat in coming years, according to the EIA, rising only about 1 percent for 2015.[read more]

Obama Administration Quietly Seeks Extra Boost for Small Modular Nuclear Reactors

March 26, 2015 by Stephen Lacey

Last week, the president issued an executive order mandating a 40% cut in carbon dioxide emissions across government agencies. Buried in the list of qualifying clean energy technologies was a reference to small modular nuclear technologies that are smaller and less capital-intensive than light water reactors.[read more]

Could India's Coal Plans Derail the Global Climate?

March 26, 2015 by Tobias Engelmeier

India Energy Needs and Coal

If India grew its electricity system based on coal (as China has done), would it derail the global climate? Under a “coal-heavy” scenario, India would need to increase is coal-fired power generation capacity from the 156 GW in early 2015 to 677 GW in 2035. What would be the CO2 implications of such a strategy?[read more]

Energy Efficiency 2.0: A New Definition Underway in California

March 25, 2015 by Christine Hertzog

What does energy efficiency mean to you? In states like California that employ aggressive energy efficiency policies and standards from widget to building envelope, it’s been a successful strategy to reduce per capita energy consumption.[read more]

Areva Struggles to Dig Out of Debt

March 25, 2015 by Dan Yurman

Areva and Debt Problems

Phillippe Knoche stated that while Areva is committed to building two EPRs at Hinkley Point, they may be the last of their kind, and that they're abandoning the firm’s strategy of leading “high profile, new build projects” and instead will concentrate on the supply chain including major components of nuclear reactors.[read more]

Study: Solar PV in the Built Environment Could Power California Nearly 5 Times Over

March 24, 2015 by Stephen Lacey

China Energy Needs and Sources

If you follow energy discussions, you will often hear one of two visions of China’s energy system emphatically described by various pundits and advocates. At first blush, the two visions seem fundamentally in conflict. Only one must be true! How can China be both “green” and “black” at the same time?[read more]

Renewables and Future Energy Options

 

It is time for the world to get serious about renewables, by formally recognizing that nuclear energy is one in all ways that matter. Usually the term renewables is taken to mean wind and solar, but this makes the idea of a life and death contest with nuclear all the more ridiculous.[read more]

Big Data Increasing Power Generation Reliability and Saving Money, GE Says

March 23, 2015 by Jared Anderson

Big Data and Energy Reliability

Recently GE announced its ‘predictive maintenance’ program driven by operational data from the company’s global fleet of more than 1,500 gas turbines helped decrease power plant downtime and saved customers an estimated $70 million in 2014.[read more]
