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.

Figure 1. Natural and nature-based features at a glance.

NATIONAL WILDLIFE FEDERATION
This report represents a collaborative effort of the National Wildlife Federation, Allied World Assurance Company, and Earth Economics to address the mounting risks of flooding and hurricanes to U.S. communities. Specifically, this report focuses on the U.S. coasts and coastal waters of the Atlantic and Pacific Oceans and the Gulf of Mexico and the nation’s extensive network of rivers and streams –places where millions of Americans live and work. It asks whether federal, state, and local officials are paying enough attention to the growing threats of floods and hurricanes across the country and whether they are using the policy tools at their disposal to protect people and property endangered by these potentially-catastrophic natural hazards.

ELECTRICITY GENERATION BY SOURCE, 2013

AMERICAN COUNCIL ON RENEWABLE ENERGY
With the growing prominence of renewable energy in the western power, heat, and transportation sectors, states are implementing and exploring technology and policy options to effectively manage its production and use. Renewable energy is now responsible for over 20% of electricity generation in six western states, and the region saw the addition of nearly 4 GW of new renewable energy capacity in 2013 alone – which is more than two thirds of total 2013 U.S. capacity additions.

Figure 1. Reclaimed material use, 2013.

ILLINOIS CENTER FOR TRANSPORTATION
The Illinois Department of Transportation (IDOT) has many years of experience using a variety of reclaimed and recycled materials in highway construction. Major material use in highway construction is in the form of aggregates, concrete, and hot-mix asphalt (HMA). It should be no surprise that reclaimed and recycled material use is aligned with usage of these basic construction materials. This report presents the quantity of materials used in 2013, along with specific reporting as required in Illinois Public Act 097-0314. Specific reporting on use of shingles, along with efforts to reduce the carbon footprint and to achieve cost savings through the use of recycled and reclaimed materials, in asphalt paving projects is presented.
