Surviving the Debate over Renewable Energy Tax Credits

October 13, 2015 by Dan Liggett

Renewables and Tax Credits

While politicians continue to debate the Production Tax Credit and Investment Tax Credit, renewable energy companies can turn to equipment and technology improvements to keep costs down.[read more]

Distributed Batteries Offer Value Far Beyond Demand-Charge Reduction

October 9, 2015 by Katherine Tweed

Battery Benefits

In the U.S., behind-the-meter energy storage is mostly sold to offset commercial peak demand charges. The business case works today in states such as California and New York, but it also leaves most of the battery’s value on the table, according to a new report from Rocky Mountain Institute.[read more]

3 Ways Public Dollars Can Embrace Risk, Catalyze Emerging Market Clean Energy

October 7, 2015 by Justin Guay

Energy Investment Risk and Public Funding

It's easy to feel as though clean tech is an unstoppable juggernaut when you see unfathomably large clean energy targets in emerging markets like India. But unless those of us with mandates that go beyond making money embrace risk we could strand the development of important clean tech markets.[read more]

Community Solar: PV for the Rest of Us

October 2, 2015 by Coley Girouard

Community Solar and Local Energy

More and more, across the U.S., consumers want access to solar energy. However, only 13.5% of homes have rooftops suitable for solar. In what many are hailing as the solution - community solar - the remaining 86.5% of households could benefit from solar power as if the panels were installed on their homes.[read more]


Change Ahead: Cutting Carbon from U.S. Highways

October 1, 2015 by Wisconsin Energy Institute

Highway Carbon Costs

What will it take to make a cross-country drive in a light duty vehicle a low-carbon pursuit? According to Paul Meier, it will take a combination of three advances: a large increase in the adoption of electric vehicle use, a huge uptick in biofuels production, and a change in the habits of U.S. drivers.[read more]

Rethinking ESS Certification: Is There a Better Way?

September 21, 2015 by James Greenberger

A binary, pass-fail system of certification for ESS systems threatens a dangerous disconnect between public interest and private industry. While minimum safety standards are necessary, real progress in ESS safety will come only when safety becomes an inseparable part of the economics of energy storage.[read more]

Bridging Waves with Service Operation Vessels

September 21, 2015 by René Cornelis Wigmans

Offshore Wind Operation Vehicles

Far from the coast, the winds are strong. This is the ideal place for offshore wind farms, and it is precisely here, thanks to the trend towards renewable energy, that large wind farms are being built. Yet until now, no appropriate maintenance concept for these high-performance power stations has been developed.[read more]

Study: Electric Vehicles Can Dramatically Reduce Carbon Pollution from Transportation, and Improve Air Quality

September 18, 2015 by NRDC Switchboard

Air Quality and Transportation

Producing the electricity to power electric vehicles can generate emissions. But those emissions levels are far lower than the pollution emitted by conventional vehicles, and could be even lower as the electric power sector cleans up over next few decades, according to a new report issued recently.[read more]

Texas Mulls the Market Power of Distributed Energy Resources

September 17, 2015 by Jeff St. John

Texas and Resource Decisions and Policy

Over the course of this summer, the Republic of Texas grid operator ERCOT started working on ideas for opening the state’s energy markets to distributed energy resources, by allowing the grid-scale aggregation of rooftop customer-sited generators.[read more]

A New Dawn for Energy Efficiency Financing

September 16, 2015 by Clare Taylor

Energy Efficiency Financing

Energy efficiency remains one of the most stubborn energy transition challenges. The money is on the table, but the market is yet to take off. Now a ground-breaking project is developing standardized processes for bankable projects on a massive scale. Is investor confidence the key to unlocking the world’s ‘first fuel’?[read more]

Offshore Service Operation Vessels: From Idea to Completion

September 15, 2015 by René Cornelis Wigmans

Offshore Wind and Construction Vessels

The wind energy sector is growing and growing – and its services must also keep up to speed. Siemens developed a concept to tackle this at an early stage, and has opted to deploy offshore service operation vessels (or SOVs for short). Two of these vessels are now in operation.[read more]

Solar Will Soon Be the Dominant Generation Source for Microgrids

September 15, 2015 by Katherine Tweed

Solar and Microgrids

Trane and Alstom Grid were recently awarded $5 million from the California Energy Commission (CEC) to build a wastewater treatment microgrid that will incorporate solar energy at the Laguna Wastewater Treatment Plant in Santa Rosa, California.[read more]

Landmark Climate Law Directs Electric Utilities to Displace Oil Companies

September 14, 2015 by Max Baumhefner

Climate Law and California

Within 15 years, California will generate at least half of its electricity from renewable resources and double savings from energy efficiency gains, two milestones included in Senate Bill (SB) 350. News coverage of this bill prior to its passage overlooked these monumental targets.[read more]

September 3, 2015 by Tom Schueneman

Prepping for Paris

One of the final rounds of climate talks are now underway in Bonn, Germany as the international community makes final preparations for the upcoming COP21 climate conference in Paris where nations hope to hammer out a binding international treaty on climate change.[read more]

Alaska Increases Wind Power Capacity in Utility - and Distributed-Scale Projects

September 2, 2015 by U.S. EIA: Today in Energy

Alaska and New Energy

Although wind power provided less than 3% of Alaska's electric power generation in 2014, Alaska's wind power capacity has increased 20-fold between 2007 and 2014, growing from 3 megawatts (MW) to 60 MW. This increase is notable in light of the challenges of installing and connecting large wind generators.[read more]
