Clean Energy Conferences Roundup: March 2015

By EDF Blogs / Published: March 2, 2015

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 March:

Mar 6-8: Global Clinton Initiative University Meeting (Miami, FL)
Speaker: Miriam Horn, Special Projects

President Clinton and Chelsea Clinton will host the eighth annual Global Clinton Initiative University (CGI U) Meeting at the University of Miami. The meeting will bring together more than 1,000 innovative student leaders to make Commitments to Action in CGI U’s five focus areas: education, environment and climate change, peace and human rights, poverty alleviation, and public health. Through the CGI University Network, The Resolution Project, and other opportunities, over $900,000 in funding opportunities will be available to select CGI U 2015 students to help them turn their ideas into action.

If Time-Variant Electricity Pricing Offers So Many Benefits, Why Don’t We Have More of It?

By Elizabeth B. Stein / Published: March 2, 2015

With time-variant pricing, people can choose to run their dishwashers at times of day when electricity is less expensive.

Today, most residential electricity customers are charged the same price regardless of when the electricity is actually being used. Charging customers a uniform price for electric service looks a bit like buying groceries by the cart instead of by the items purchased (e.g., apples versus filet mignon) – simple, to be sure, but so riddled with inefficiencies that no one would actually propose operating a supermarket that way. A cartful of filet mignon may weigh the same as a cartful of apples, but the value of these items and the cost of bringing them to market is drastically different. Similarly, electricity costs differ depending on the time of day power is produced and delivered.

Time-variant electric pricing addresses this issue by charging customers different prices depending on when electricity is used, reflecting the true costs of producing and delivering electricity. This gives customers greater control over their electricity bills by allowing them to reduce their energy use at higher-cost times. A recent blog post by my colleague, economist Beia Spiller, explained how time-variant electricity pricing can benefit customers, utilities, and the environment, and described several different types of time-variant pricing.

Given its compelling economics, one would think time-variant pricing would be widespread. Part of the reason it’s not is sheer inertia, but there’s more to it than that. Read More »

Oil and Gas Lobby Says Up Means Down

By Mark Brownstein / Published: February 27, 2015

Marcellus_Shale_Gas_Drilling_Tower_1_crop The Environmental Protection Agency just released the draft of its yearly greenhouse gas emissions inventory. It shows in no uncertain terms that methane emissions from the oil and natural gas sector are going in the wrong direction: Up.

Emissions from this overall sector are up two percent in 2013, which includes emissions from oil (petroleum) systems which were at their highest levels ever since estimates began in 1990 – and up 68 percent since 2005. Emissions from natural gas processing, where impurities are removed to produce pipeline quality gas, are up 38 percent since 2005. From transmission and storage: Up 11 percent.

Yet the industry’s public relations machine says emissions are falling. So what’s the disconnect? Read More »

Ohio Electricity Regulators Reject Bailout for Uneconomic Power Plants

By John Finnigan / Published: February 27, 2015

Ohio’s clean energy economy celebrated a big win this week. The Public Utilities Commission of Ohio (PUCO) denied American Electric Power Company’s (AEP) request for guaranteed profits to operate its aging, uneconomic coal power plants. EDF, along with many other parties, opposed AEP’s proposal.

EDF applauds the Commission for recognizing AEP’s proposal would not benefit Ohio residents and businesses. These old coal plants cost more to operate than the value of power they generate. Plus, they produce harmful greenhouse gas emissions which, if the plants continue to operate, would make it more difficult for Ohio to comply with the Environmental Protection Agency’s (EPA) proposed Clean Power Plan, which would set the first-ever limits on carbon emissions from existing power plants.

The Public Utilities Commission’s decision sends a clear message: power companies can no longer rest on their laurels. Clean energy businesses, entrepreneurs, investors, and Ohioans are ready for a new era – one in which utility profits are not placed ahead of Ohio’s best interests.

With gas prices low, an increased use of renewable energy, and weak demand resulting from customer energy efficiency improvements, some utilities like AEP are now burdened by their heavy reliance on coal – and looking to their customers to bail out their uneconomic power plants. Thankfully, yesterday’s decision assures that the market will remain competitive, giving clean energy resources an equal opportunity to compete with legacy fossil fuel plants. Read More »

Efficiency is what Texas Can (and Should) Do Best

By John Hall / Published: February 25, 2015

I have been involved in Texas’ energy sector for a long time, particularly from an environmental perspective.

I was there when the state’s metropolitan centers and their robust industrial sectors were challenged to reduce ozone-forming pollution. I was there when Texas deregulated its energy market to increase competition, improve choices for residents and businesses, and lower electricity prices. And now, I’m here to witness the state’s transition to a clean energy economy – one that harnesses more West Texas wind energy, rooftop solar, and natural gas (with the right controls in place) than any other time in history.

The one thing that ties all of these events together is efficiency – something Texas has led in the past.

Energy efficiency is Texas’ most cost-effective way to reduce energy use and carbon pollution from power plants. It also creates other benefits to the power grid, like improving reliability and lowering costs for infrastructure maintenance. Plus, saving energy saves water, which is critical in a state like Texas under the pressure of a multi-year drought. Read More »

Clean Energy is Just Smart Business for Leaders like Apple, Google

By Peter Sopher / Published: February 24, 2015

Apple and Google have changed our lives forever, both because of their technological innovations and sheer size as global corporations. Now, they’re aiming to reshape the energy landscape.

This month, Apple announced plans to spend nearly $2 billion on European data centers set to run entirely on renewable energy, and invested $848 million to secure power from 130MW of First Solar’s California Flats Solar Project under a 25-year power purchase agreement. Google also agreed to replace 370 wind turbines installed in the 1980s with 24 new, more efficient and bird-friendly turbines at the Altamont Pass in the San Francisco Bay Area. Moreover, there has been recent speculation Apple may be working on an electric vehicle to challenge Tesla’s dominance in that market.

These developments are impressive on their own, but they are also part of a new trend among major corporations – whose primary focus is not energy generation – proactively pursuing clean energy projects. So, why are they doing this?

For corporations whose businesses do not rely on fossil fuels, aligning themselves with clean power is proving a prudent move both financially and for public relations. Read More »
