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.

Twin Cities, MN: Water Sustainability in the Northeast Metro Area

Thursday, January 1st, 2015
Figure 1. Saint Paul Supply System Schematic

METROPOLITAN COUNCIL
The primary objective of this study is to understand the relative costs and implementation considerations of different approaches to water sustainability. The northeast metro provides a study area for this evaluation. The Minnesota Legislature requested this part of the metro area to be studied specifically, given the continued concern over lake levels and the interaction of groundwater and lakes in the area, especially White Bear Lake. The study area includes 13 communities. The results will be incorporated in the Twin Cities Metropolitan Area Master Water Supply Plan. The study will be referenced to support future planning of metro area water supplies and water sustainability practices.

More Wind, Less Warming

Figure ES-1. A Path to 30 Percent Wind Electricity

ENVIRONMENT TEXAS
American wind power is already significantly reducing global warming pollution. In 2013 alone, wind power averted 132 million metric tons of carbon dioxide emissions – as much as would be produced by 34 typical coal-fired power plants. But with the United States and the world needing to move toward a future of 100 percent clean energy in order to prevent the worst impacts of global warming, America must do much more.

INTERSTATE RENEWABLE ENERGY COUNCIL

One significant lesson that is apparent upon reviewing the wide variety of existing state standards is that inconsistency is the nemesis of clean energy development. It creates confusion among consumers, undermines the ability of businesses to operate efficiently across utility service territories or state lines,
and increases costs to all program participants — utilities, consumers, businesses and commission staff — by forcing these stakeholders to master the idiosyncrasies of each individual state’s programs.

The Impacts of EPA’s Clean Power Plan on Electricity Generation and Water Use in Texas

Tuesday, December 9th, 2014
Figure 3. Baseline power generation fuel mix, where coal is gradually replaced by gas and wind power (Units = GWh/yr)

CNA CORPORATION
To determine how Texas could be affected by the U.S. Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP), we applied CNA’s Electricity-Water-Climate power sector model to evaluate the potential impacts. We find that under the CPP, the state will save water and reduce levels of conventional air pollutants. In addition, the state will be able to meet the policy’s targets with modest incremental effort even though electricity demand is expected to increase by 25 percent.
