Momma Said ‘Time-of-Use’ Electricity Pricing

My mom is a pro at shopping for good deals. She taught me the importance of timing my purchases during the off-peak season to get the most value for my dollar.

Time-of-Use (TOU) electricity pricing reminds me of the lessons my mom taught me, and it can help empower families to take control of their energy use, while saving money AND improving air quality.

Like the name implies, TOU pricing allows customers to choose when to power-up large appliances (think laundry, dishwasher, A/C) in order to avoid using high-demand, “peak” energy – which is more polluting and expensive. It is a voluntary program with a proven track record.

Peak energy demand typically occurs late in the afternoon when everyone is coming home from school and work, running the A/C, charging phones, cooking, doing laundry, or streaming Netflix on a T.V. During this high-demand time, energy prices spike and electric utilities flip on expensive and dirty fossil fuel “peaking” power plants to meet energy demand (because nobody wants to lose power and heaven-forbid the Internet!).

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.

EDF is Calling for More Demand Response in California and Why You Should Too

This week the California State Assembly will consider Senate Bill 1414 (Wolk). What’s so exciting about SB 1414? This bill will accelerate the use of demand response (DR), a voluntary and cost-friendly program that relies on people and technology, not power plants, to meet California’s rising electricity needs.

DR programs compensate people and businesses who volunteer to use less electricity when supplies on the power grid are tight and/or to shift energy use when cleaner, renewable resources are available. Every time a customer participates in lowering their energy use through demand response, they are rewarded with a credit on their electricity bill.

The implementation of demand response will help catalyze a much needed upgrade to our outdated grid, whose fundamental design hasn’t been updated since Thomas Edison invented it over a century ago. Demand response can empower participants to lower their electricity bills and carbon footprints, improve air quality, allow for more renewable electricity, and enhance electric grid reliability. In a tree of options for modernizing and cleaning up our energy system, demand response is a low-hanging-fruit. Read More »

The 2014 U.S. Clean Tech Leadership Index: Did your State, City Make the Cut?

cleantech indexjpgIf there is one thing that works in the world of advocacy, it is a ratings table that shows how one state, metropolitan area, or utility compares to its peers. The latest report, U.S. Clean Tech Leadership Index, from Clean Edge does just that.

The fifth annual U.S. Clean Tech Leadership Index finds that California, Massachusetts, Oregon, Colorado, and New York lead the way among states in solar and electric vehicle adoption, with smart climate policies and clean energy financing driving the clean tech leadership index growth.

Clean energy is becoming a popular choice for mainstream America with 11 states now generating more than ten percent of their electricity from non-hydro renewable sources, according to the Clean Edge report. As seen in the graph below, Iowa leads the way in utility-scale wind, solar, and geothermal electricity generation. Read More »

The cheapest way to cut climate pollution? Energy efficiency

This blog post was co-authored by Kate Zerrenner, an EDF project manager and expert on energy efficiency and climate change.

On June 2, the U.S. Environmental Protection Agency made a historic announcement that will change how we make, move and use electricity for generations to come.

For the first time in history, the government proposed limits on the amount of carbon pollution American fossil-fueled power plants are allowed to spew into the atmosphere.

There are two clear winners to comply with the plan while maintaining commitment to electric reliability and affordability: energy efficiency and demand response.

We’re already seeing pushback from some of our nation’s big polluter states, such as West Virginia and Texas. But the truth is that while the proposed limits on carbon are strong, they’re also flexible.

In fact, the EPA has laid out a whole menu of options in its Clean Power Plan – from power plant upgrades, to switching from coal to natural gas and adopting more renewable energy resources. States can choose from these and other strategies as they develop their own plans to meet the new standards. Read More »

Nest’s Promising Results for Reducing Peak Electricity Demand

Back in January when Google announced it would spend $3.2 billion to purchase Nest, EDF knew this was a company to watch. The results of three new reports, released today, confirm that controllable thermostats like the Nest Learning Thermostat are both customer-friendly and useful for energy system planners. Moreover, the reports signal that smart devices, such as those Nest manufactures, have potential for generating marked savings for utility customers.

The reports analyze 2012-2013 energy use data gathered from four major utilities across the U.S. that offer Nest energy services programs: Austin Energy, Reliant Energy, Green Mountain Energy, and Southern California Edison.

The first report evaluates the results of Rush Hour Rewards, a demand response service that changes the temperature of the homes of Nest users during energy “rush hours”, or times when demand on the grid is highest. The second examines Seasonal Savings, a program that runs for three weeks and slowly modifies the temperature according to the customer’s behavior (which this smart thermostat is able to ‘learn’ via its built-in motion sensor and understanding of its owner’s temperature preferences). Both operate during times of heavy usage, namely winter and summer. The third report analyzes home energy data of Nest customers more broadly, comparing energy use before and after the installation of a Nest Thermostat. Read More »
