Environmental Defence Fund’s signature energy efficiency initiative has gone international. EDF Europe/UK today rolled out the Investor Confidence Project Europe (ICP Europe), aimed at boosting private sector investment in European energy efficiency renovation projects in the building sector.

As Director of ICP Europe, I was thrilled to introduce the initiative with leaders from the financial, engineering, and government communities at an event in Brussels during a week when two of Europe’s largest energy efficiency events are being held: Renovate Europe Day and Building Performance Institute of Europe ‘s Efficiency Investors Day.

The potential for renovating existing buildings in Europe to reduce the impacts of climate change, generate financial savings, and create jobs is considerable – and largely untapped. Estimates say that large-scale energy efficiency efforts in Europe could reduce carbon emissions by 932 million metric tons, equivalent to taking nearly 200 million cars off the road, and create more than 1 million new jobs in the building industry by 2050.

Cost-Benefit Analysis of Utility-Scale Energy Storage is Promising

By EDF Blogs / Published: November 4, 2014

By: Ellen Shea, Analyst, EDF Climate Corps

I recently read a white paper by Chet Lyons of the Energy Strategies Group performing a cost-benefits analysis of utility companies purchasing battery storage systems vs. simple cycle gas-fired combustion turbines (CT). These CT systems are typically used to regulate peaking capacity. The article shows how storage systems can be a great solution for utilities companies to keep up to date with the changing trends in energy in the US.

Lyons states that as we shift to using more and more renewable energy sources (such as solar PV), the electricity grid needs to be able to be more flexible to the fluctuations in supply of wind, solar, etc. In other words, we have to be able to better support the peaking capacity of the grid.

The paper makes the case for using energy storage systems as a way to meet the peaking resource needs of the grid from renewables, and also as a way for utilities to recoup some lost revenues. Lyons examined a new flow battery storage system by ViZn Energy and found it to be more effective, faster, and more flexible than traditional CTs. Additionally, following solar PV’s trend of declining costs, he believes that in the next three years these battery storage systems will be cost competitive with CTs. Read More »

5 Energy Trends that will Change the Balance of Power

By EDF Blogs / Published: November 4, 2014

By: Dan Upham, Editor

We no longer fret over taxes on tea, but there’s another American Revolution forming in our great nation today. Like the colonist uprising 241 years ago, it’s fueled by a need to stand up against an outdated system that threatens our way of life.

It’s a battle over the future of American energy and our antiquated electric grid. And it centers around the way consumers, utilities, and investors interact with this vast network of powerlines, substations, and plants.

As Cheryl Roberto, who leads Environmental Defense Fund’s Clean Energy program, notes, “The U.S. is poised to spend around $2 trillion over the next two decades replacing our outdated electric infrastructure.”

That’s a lot of coin and a tremendous opportunity. Read More »

USDA Loan Improves Energy Efficiency in Rural North Carolina

By Marilynn Marsh-Robinson / Published: November 3, 2014

A rural electric cooperative in North Carolina is one of the first in the country to receive funds from a new United States Department of Agriculture (USDA) on-bill finance program that will help customers improve energy efficiency, lower utility bills, and reduce carbon pollution. Roanoke Electric Membership Cooperative, which serves 14,ooo rural customers, is in my home state.

Roanoke Electric’s membership base is similar to other economically distressed rural areas, which have a growing elderly population and residents with homes that need energy-saving upgrades.

The cooperative diligently promotes energy efficiency, yet there are still customers with utility bills that are higher than their mortgage payments some months. Securing upfront capital to finance home improvements can be challenging. Read More »

Clean Energy Conferences Roundup: November 2014

By EDF Blogs / Published: October 31, 2014

Each month, the Energy Exchange rounds up a list of top clean energy conferences around the country. Our list includes conferences at which experts from the EDF Clean Energy Program will be speaking, plus additional events that we think our readers may benefit from marking on their calendars.

Top clean energy conferences featuring EDF experts in November:

Nov 3-4: Smart Cities Conference, San Diego, CA
Speaker: Kate Zerrenner; Project Manager

Featuring presentations from innovative utilities, advanced solution providers, and insights from leading experts, Smart Cities attendees will walk away with a roadmap to shape the convergence of energy infrastructure and public services. The conference will also focus on maximizing utility plans, people, and processes to evaluate the performance of grid investments and evolving revenue streams. Read More »

5 Reasons Virtual Net Metering is Better than Plain Ol’ Net Metering

By Dick Munson / Published: October 30, 2014

Several states have embraced net metering in order to encourage the adoption of solar energy and other distributed generation. Sometimes referred to as “running a meter backwards,” net metering allows people to generate their own electricity, export any excess electricity to the grid, and get paid for providing this excess energy to the utility who may use it to power nearby homes or manage overall electricity demand.

Net metering leads to lower – or in some cases negative – electricity bills without having to invest in expensive batteries to store excess energy, which can be cost-prohibitive. By generating energy on-site where it’s consumed, net metering also reduces the strain on distribution systems and cuts the amount of electricity lost to long-distance transmission and distribution (estimated at seven percent in the U.S.). Net metering, moreover, tends to reduce greenhouse gas emissions by incentivizing people to adopt renewable energy and become more aware of energy-saving opportunities. Read More »
