Making the World a Better Place: One Megawatt at a Time

What does it take for a manufacturing firm with 24/7 operations to incorporate sustainability goals into its daily activities? I learned the answer to the question this summer at Owens Corning.

Owens Corning is an innovator in fiberglas™ technology operating in 27 countries around the world, with its products’ end-uses ranging from insulation and roofing shingles to wind turbines. The company has been a member of the Dow Jones Sustainability World Index for the last five years, and has rallied around climate change issues to achieve key milestones in its energy intensity and greenhouse gas reduction goals since 2002. Having picked the so-called “low hanging fruits” in energy efficiency, Owens Corning now aspires to purchase 100 percent of its primary energy from renewables. In this, the company’s most recent milestone has been the installation of the largest onsite solar PV system in New York State funded by the New York Sun program in 2013.

One reason this has been possible is due to a shift in the cost of renewable technology, with solar and wind approaching grid parity in some regions of the United States. This has provided an opportunity to enter the renewables space that did not exist a few years back. Technologies like net metering, which allows businesses to sell excess clean energy back to the grid and profit from their renewable deployment, and availability of third party energy suppliers in some states, as well as a means to track and retire the renewable certificates and the reporting standards that have emerged around these, have all been crucial for enabling this shift towards greater renewables.

Solar in Texas: It’s Really Happening this Time (Really)

By Marita Mirzatuny / Published: September 23, 2014

Every year, it seems, is predicted to be the “year for solar,” and for certain states this may ring true.

But in Texas, despite having a close relationship with the sun and its heat (2011 gave us 100 days over 100 degrees and no rain), we have yet to realize our potential for solar energy development, the highest potential of any state in the nation. Texas currently only has about 213 megawatts (MW) of solar energy installed (compared to over 237 MW in little ol’ Massachusetts). Recent developments, however, make me encouraged that the next few years will be the catalyst for finally fulfilling that potential.

Austin

A few weeks ago, the Austin City Council voted on an ambitious solar step forward, directing a “utility-scale solar target of 600 megawatts by 2017, a rooftop solar target of 200 megawatts by 2020, explicit language enabling third-party solar ownership, a floor price for the value-of-solar tariff…and a mandatory strategy to procure 200 megawatts of fast-response storage.” The resolution will require the municipal utility, Austin Energy, to obtain 60 percent of its electricity generation from renewables over the next decade, and to be completely carbon-free by 2030.

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

By Ronny Sandoval / Published: September 22, 2014

New York is re-examining the way energy is regulated, priced, and distributed in the state in order to emerge with a 21^st 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 »

Five Reasons Now is the Time for Federal Standards to Reduce Oil and Gas Methane Emissions

By Mark Brownstein / Published: September 18, 2014

Today sixteen leaders of the nation’s largest environmental and conservation groups, including EDF’s president Fred Krupp, came together to call for urgent federal action to curb methane emissions from oil and gas development.

This past march, President Obama laid out his Strategy to Reduce Methane Emissions, where he announced that the Environmental Protection Agency will decide by this fall how best to reduce methane pollution from the oil and gas sector. The Strategy builds on the commitment from his 2012 State of the Union Address that the development of oil and gas resources must not put Americans’ health and safety at risk.

Here are five reasons why reducing methane is a national priority that requires the Obama administration to follow through on its commitment:

Illinois Considers Greenhouse Gas Metric for Evaluating Utility Performance

By Dick Munson / Published: September 12, 2014

Source: pgegreenenergy

A new utility business model – “Utility 2.0” or “reform” – is the hot topic in statehouses and regulatory commissions across the country. This is due to many factors: technological innovations in the energy sector, changing consumer expectations, increasing electricity prices, tighter regulations, and the need to decarbonize our energy sector as we grapple with climate change.

Some argue utility earnings should be based on performance rather than volumetric electricity sales. They suggest utilities’ monopoly interests should be aligned with enabling clean energy services – such as on-site renewable energy and home energy management – instead of simply delivering more electricity.

Key to this new approach is the ability to define – and then measure – performance. This will require a set of metrics by which utility investments can be judged and rewarded. Illinois was the early adaptor of performance-based metrics for its historic smart meters roll-out and is finalizing a set of metrics this week that are critical to designing a utility business model for the future.

What a Difference a Day Makes! The Value of Real-Time Electricity Data

By Gavin Purchas / Published: September 11, 2014

Imagine you’re trying to lose weight. If you step on the scale once a month, how can you possibly know how each of your daily decisions affects the number? Weighing yourself every day would be a step up, giving you a much clearer picture of the effects of each day’s choices. Now imagine the potential results if you could access real-time data – if you were able to see just how many calories were in each food you picked up, as well how much energy you were exerting at any given moment.

Thanks to a meta-analysis on behalf of the American Council for an Energy Efficiency Economy (ACEEE), we can now see that access to this kind of granular, real-time data on electricity use leads to significant household electricity savings.

Survey highlights importance of timeliness and granularity

The ACEEE survey aggregates multiple studies designed to evaluate the effectiveness of different types of electricity customer feedback from the past 20 years, including 61 trials from around the world: 33 from the U.S., 13 from Europe, 9 from Canada, and 3 others. Such a diverse pool allows us to draw important conclusions about consumer energy use habits while controlling for variations in culture, climate, and energy use patterns. The results are displayed in the graph below. Read More »
