Wind Energy Helps Build a More Reliable and Balanced Electricity Portfolio

Wednesday, February 25th, 2015
U.S. Wind Energy Share of Electricity Generation by State During 2013

AMERICAN WIND ENERGY ASSOCIATION
Some of the most common questions about wind energy focus on how wind can be reliably integrated into the power system. A key source of confusion is that, contrary to most people’s intuitive experience that winds are variable and electricity demand and supply is stable, the opposite is actually true at the grid operator scale. The following report answers 15 of the most frequently asked questions with lessons learned from grid operators’ experiences reliably integrating large amounts of wind. Concise answers to these questions are provided here in the executive summary, while citations and explanations of the supporting data and analysis for those answers can be found by following the hyperlinks to the relevant sections of the full report below.

EPA’s Clean Power Plan and Reliability

THE BRATTLE GROUP
The United States (“U.S.”) power system is undergoing a fundamental transformation, largely driven by advances in technology and low natural gas prices. This transformation is putting significant pressure on existing coal-fired and even nuclear generation, increasingly leads to renewable energy resources being cost-competitive with fossil-fired generation, and results in myriad choices for consumers that promise to permanently alter the role of demand in the power system. As a consequence, the fuel mix and associated emissions of the U.S. power system are changing rapidly, as are the actions taken by system operators to manage the quickly evolving electric system.

2015 Strategic Directions: Smart Utility Report

Monday, February 2nd, 2015
Figure 1 What do you see as the primary driver of smart city initiatives in your region?

BLACK & VEATCH
Now more than ever, the increasing use of technology offers utility operators greater understanding of their networks and how customers consume power, water, natural gas and data. Forecasting historically required large teams to examine past operations and create an operations snapshot, often long in the past. Now, predictive analytics, or Adaptive Planning, is redefining how complex systems can be managed through rapid analysis of real-time information.

Boston: Methane Emissions from Natural Gas Infrastructure

Thursday, January 29th, 2015

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA (PNAS)
Most recent analyses of the environmental impact of natural gas have focused on production, with very sparse information on emissions from distribution and end use. This study quantifies the full seasonal cycle of methane emissions and the fractional contribution of natural gas for the urbanized region centered on Boston. Emissions from natural gas are found to be two to three times larger than predicted by existing inventory methodologies and industry reports. Our findings suggest that natural-gas–consuming regions may be larger sources of methane to the atmosphere than is currently estimated and represent areas of significant resource loss.

Going Solar in America: Ranking Solar Value to Consumers

Monday, January 26th, 2015
Overall City Rankings

Most Americans are unaware of the true financial value of solar today. Seen by many as a technological luxury, solar energy is not seriously considered as an option by most homeowners in the U.S. However, our analysis shows that, in 46 of America’s 50 largest cities, a fully-financed, typically-sized solar PV system is a better investment than the stock market, and in 42 of these cities, the same system already costs less than energy from a residential customer’s local utility…So why aren’t more Americans investing in solar? There is a clear information gap, and with this report, we intend to open the eyes of average homeowners by showing that solar can generate both significant monthly savings and long-term investment value, and not infrequently, cost less than energy from some of America’s largest electric utilities.

Wind Energy Saves Consumers Money

Monday, January 12th, 2015
Wind Energy Chart

AMERICAN WIND ENERGY ASSOCIATION
Wind energy’s consumer benefits stem from wind energy’s fuel price stability. Wind is one of the few energy sources that offers perfect fuel price stability that can be locked in up front, as wind’s fuel cost will always be zero. For all other major conventional sources of electricity, fuel prices cannot be locked in for the long term and are often set by the spot market. The costs of these fuel price increases and risk are passed directly on to consumers through their electric bills. In contrast, wind energy is more like a fixed-rate mortgage, locking in the fuel price for the life of the power plant.

Our Energy Tomorrow: The State of American Energy

Friday, January 9th, 2015
hydropower

America now occupies a position of energy leadership that was unthinkable a short time ago. Gone are the days of uncertainty and concern over having the supply of energy we need, when we need it. Today, the United States is the world’s top producer of natural gas, the world’s leading refiner of petroleum products, and very soon could be the leading producer of oil…But this is only part of America’s larger energy story. The United States is in the midst of a new era in domestic energy abundance characterized by rising use of renewable energy and increased oil and natural gas production that is strengthening our economic outlook and enabling America to emerge as a global energy superpower.
