Germany's Energiewende Proves Electricity can be Clean and Reliable

electric-power-273644_640Since 2004, the year of the first major revision of Germany’s Renewable Energy Act (EEG), the country has added at least 35 gigawatts (GW) of solar and 35 GW of wind to its electric grid – enough to offset upwards of 35 coal plants. What’s more impressive is during the first half of 2014, close to 29 percent of Germany’s electricity came from renewable sources. For perspective, America’s renewables percentage, at about 14 percent, was half of Germany’s during this timeframe.

Meanwhile, the country has improved its status as a grid reliability leader, causing the Heinrich Böll Foundation’s Energy Transition blog to conclude, “Clearly, installing the equivalent of 100 percent of peak demand as wind and solar capacity does not bring down the grid.”  Renewables International further asserts, “Renewables have not yet reached a penetration level that has detrimentally impacted grid reliability.”

This success runs contrary to the predictions of Energiewende’s critics, who have sounded the alarms about investing in “too much” renewable energy. Some of these concerns are more valid than others, but the truth is, most of these claims are blown out of proportion, fixable with solutions that are not overly complex, and/or based on no empirical data.

Utility 2.0: New York State Envisions New Platform Giving Equal Priority to Clean Energy Solutions

brooklyn-bridge-71800_640New York’s “Reforming the Energy Vision” (REV) proceeding aims to reform the state’s long-standing electricity system to lay the groundwork for a cleaner and more efficient grid that allows for more customer choice and competition from third-party energy services companies. Forming the centerpiece of this 21st-century vision is a platform that would smoothly integrate innovative energy services and solutions into the existing grid, allowing them to compete on equal footing with electricity from centralized power plants.

Currently, the electric industry comprises three functions: generation, transmission, and distribution. Generation refers to making electricity, traditionally from large, centralized power plants. Transmission refers to sending that electricity along high-voltage wires to substations closer to electricity customers. Distribution refers to delivering the power from the substations to homes and businesses. In its recent straw proposal, the Department of Public Service Staff (Staff) recommends splitting the distribution function into two parts, one performing the traditional delivery service and the other serving as the Distribution System Platform Provider (DSP), to grant equal priority to energy solutions that are not centralized, such as on-site, distributed generation and energy efficiency.

Companies Turn to Technology to Engage Consumers in Smart Energy Management

By: Claire Dooley, student at the Bren School of Environmental Science & Management

claire_dooley_blog_0Most of us in America would argue that affordable and reliable energy access is a basic life necessity, possibly even a basic human right. However, JD Power & Associates recently reported that only 3% of consumers are actually reviewing their energy usage more than once a month. Interaction with this commodity is almost entirely passive. Utilities do whatever it is they do to keep the electrons flowing, and we pay the bill.

With all of the public attention that energy’s impact on climate change has received in recent months—including IPCC findings that human-induced global warming is unequivocal and a new EPA regulation on coal-fired power plants—consumer awareness and interest in curbing our reliance on dirty energy is on the rise. Concurrently, the massive influx of residential clean energy technologies is providing unprecedented opportunity for the public to participate in climate change solutions. Read More »

New Jersey Transit Becomes a Leader in Microgrids

Superstorm Sandy crippled much of New Jersey’s critical infrastructure when it swept through the state two years ago. Stuck without power at home, many of the state’s residents also couldn’t get to work because the operations center for New Jersey Transit (NJ Transit) flooded, damaging backup power systems, emergency generation, and the computer system that controls train operations.

New Jersey is doing its best to make sure that won’t happen again. After a highly competitive grant process, NJ Transit last week received $1.3 billion in federal funds to improve the resilience of the state’s transportation system in the event of devastating future storms. The funds include $410 million to develop the NJ TransitGrid into a first-of-its-kind microgrid capable of keeping the power running when the electric grid goes down.

Microgrids are different from traditional electric grids in that they generate electricity on-site or nearby where it’s consumed. They can connect to the larger grid or island themselves and operate independently. Read More »

EDF Debuts Clean Energy Video and Raises a Glass to Austin and Pecan Street Inc.

Last night, EDF, CleanTX, Pecan Street Inc., and Google hosted one of the clean energy events of the season.

We brought everyone in the Austin clean energy community – from legislators to cleantech entrepreneurs to EDF members – together to celebrate the tremendous progress our great city has made as a clean energy leader over the years, serving as an incubator and hub for some of the most exciting and innovative companies in the clean tech sector. After all, it is the collective hard work and dedication of everyone that put Austin on the map as a global leader in the clean energy economy.

We also kicked off the evening with a screening of our new video that highlights what the smart grid is doing for American energy. Set in Austin’s Mueller neighborhood, one of the world’s largest green-built communities and Pecan Street Inc.’s testbed for energy innovation, this short film tells the dynamic story of a clean energy future from within the American home. It gives people who live in a connected community a chance to express what clean energy means to them personally, from independence and innovation to health and reliability. The heroes of the film are ordinary people from the community who are part of this quiet revolution.

Utility 2.0: Optimizing Energy Use by Making Customers Part of the Solution

New York is re-examining the way energy is regulated, priced, and distributed in the state in order to emerge with a 21st century business model. This change will deliver on a broad range of objectives, including increased customer value and environmental benefits, among others. However, achieving greater system efficiency could lead to the most impactful outcomes for customers, the environment, and society as a whole. Not only does increasing system efficiency have the potential to significantly reduce costs, energy use, and carbon emissions, it also makes the customer an integral part of the solution to meeting our future energy needs.

The challenge

Electric utilities are tasked with meeting consumer demand for electricity at all times and, until now, have done so primarily by installing additional infrastructure on the electric grid whenever needed. While this has resulted in a fairly-reliable way to meet our energy needs, it has and continues to be extremely expensive and inefficient given the evolution in how energy is used today. Read More »
