When the door to one power plant closes, a window to more clean energy solutions opens.

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? San Diego Gas & Electric (SDG&E) is certainly trying to convince Californians this is true. Trouble is, EDF and other environmental groups, along with the California Public Utilities Commission (CPUC), aren’t buying it. And you shouldn’t either.

This story begins in 2013, when the San Onofre Nuclear Generating Stations (SONGS) permanently closed, shutting down a nuclear power plant with a capacity of 2,200 megawatts (MW) and sparking a debate about how to replace this lost power source. When first determining how to proceed in the wake of the SONGS closure, the CPUC decided SDG&E could buy between 500 to 800 megawatts (MW) of new energy resources by 2022. Further, at least 200 MW of this power had to – and all of it could – be met with preferred resources like energy efficiency, renewable energy, energy storage, and demand response (an energy conservation tool that pays people to save energy when the electric grid is stressed).

Here Comes the Sun: How California is Bringing More Renewables to the Grid

rp_Larissa-Koehler-200x300.jpgAsk most people what the Beatles and California have in common and they might very well be at a loss. However, the answer is pretty simple: they are both unabashed trendsetters in the face of resistance – the former in their musical style and the latter in its clean energy policies.

Not content with setting a Renewable Portfolio Standard that ends at 2020, Governor Jerry Brown and state legislators are pushing for the Golden State to get 50 percent of its energy from renewable resources by 2030.

To meet this ambitious target, California must build a system that is largely based on renewable electricity, like wind and solar. This is not an easy task. The primary reason? Sunshine and wind are only available at certain times of the day and can be variable during those times.

Traditionally, managers of the electricity grid have relied upon dirty “peaker” power plants – usually fossil fuel-fired and only needed a couple of days a year – to balance the grid during periods of variability or when electricity demand exceeds supply. But, in a world where 50 percent of our energy comes from renewable sources as a means to achieving a clean energy economy, we can’t rely on these dirty peaker plants to balance the variability of wind and solar.

Luckily, technology is available today that can help fill the gap of these peaker plants – and the California Public Utilities Commission (CPUC) is starting to embrace it. Read More »

Investor Confidence Project San Francisco Event Fires Up Energy Efficiency Professionals

By: Matt Golden, Senior Energy Finance Consultant

icp-sf-connect-1-300x168Last week, EDF’s Investor Confidence Project (ICP) co-hosted an energy efficiency finance networking event in San Francisco, bringing together 70 local project developers, for the first-ever SF Inter-Connect. Held in collaboration with San Francisco Department of the Environment (SF Environment) and Pacific Gas & Electric (PG&E) on November 12 at the SF Environment offices, the event gave each investor, much like in ‘speed dating’, exactly five minutes to pitch the crowd on their products, describing how they worked and what kind of projects the investor was looking for.

The Investor Confidence Project is accelerating the development of a global energy efficiency market by standardizing how Investor Ready Energy Efficiency™ projects are developed and energy savings estimates are calculated. The ICP system offers a series of protocols that define industry best practices for energy efficiency project development and a credentialing system that provides third-party validation. This leads to increased confidence among building owners and investors in the reliability of projected savings. Read More »

California Clean Energy Bill Could Open Door for Homeowners and Small Businesses

Governor Brown has the opportunity to make energy-saving upgrades possible for families and small business owners by signing Assembly Bill 1883 (Nancy Skinner- Berkeley). This bill would significantly lower the cost of Property Assessed Clean Energy (PACE), a tool which enables property owners to take advantage of energy efficiency and rooftop solar PV for their homes or buildings with no money down, allowing them to pay off the investment over time through their property tax bill.

AB 1883 would streamline the PACE process and drive down the fixed transactional costs associated with commercial projects. Lowering these transaction costs is especially important for small businesses because high transaction costs can reduce the economic viability of the smaller energy upgrades that small business typically need. AB 1883 also incorporates new options for financing rooftop solar PV through PACE, which will enable a greater number of homeowners and small businesses to qualify for cost-saving solar PV contracts.

Greening the Cleanroom at PerkinElmer

By Nkiruka Avila, EDF Climate Corps fellow

Energy efficiency is an essential part of climate change mitigation, which is my primary motivation for becoming an Environmental Defense Fund Climate Corps fellow. My goal is to find energy and water savings at my host organization PerkinElmer in Santa Clara, California. PerkinElmer designs and manufactures medical imaging technology that tackles the world’s most critical health related challenges.

The facility I am working in this summer has a class 100 clean room (we call it “the Fab”) where 50×50 cm digital flat panel x-ray detectors are fabricated. Any impurity in the Fab could cause defects in the panels. PerkinElmer’s fabrication process is unique because each of the panels produced is kept as a whole unit and is not cut into smaller pieces. This makes it critical to produce flawless panels every time as a defect could ruin the whole panel.

Recently, I took a tour of the Fab with my supervisor, Joe Batdorf, and my EDF Engagement Manager, Serena Mau. The tour of the Fab was fascinating and revealed just how energy intensive the fabrication process is. I was impressed to see that several energy efficiency projects, headed by my supervisor, had already been implemented at the facility. Energy efficiency is not a foreign idea to PerkinElmer, and they have invested in several energy saving measures over the years. For example, PerkinElmer completed a reheat coil optimization project and replaced two inefficient boilers with efficient condensing boilers saving almost 70,000 therms of natural gas annually and eliminating over 300 tons of carbon emissions.

California Cements Latest Climate Alliance, this Time with Next-Door Neighbor Mexico

It’s been an invigorating few days for anyone looking for meaningful action to combat climate change, and especially for those following California’s global leadership in those efforts.

As a delegate to Governor Jerry Brown’s Trade and Investment Mission to Mexico, I witnessed first-hand California and Mexico sign a Memorandum of Understanding and formally agree to work together on a range of actions to address climate change.

The agreement between Governor Brown and representatives of Mexico’s Ministry of Environment and Natural Resources (SEMARNAT) and Mexico’s National Forestry Commission lays out areas where California and Mexico agree to cooperate and coordinate efforts on addressing climate change, including:

  • Pricing carbon pollution
  • Increasing renewable energy use and development
  • Addressing short-term climate pollutants
  • Cleaning up the transportation sector
  • Reducing emissions from deforestation and forest degradation

A Joint Vision for Low-Carbon Prosperity

It makes perfect sense that Mexico is California’s latest climate change and clean energy ally. After all, the relationship between the two jurisdictions runs deep.  Mexico is California’s largest trading partner, and our cultures and economic interests have undoubtedly been entwined throughout history. Both have much at stake with climate change, and this latest collaboration embraces a shared environmental vision which recognizes that a low-carbon future goes hand-in-hand with economic prosperity.
