The US Department of Energy projects that wind energy in the US could grow to 20% of electrical power generation in the US by the year 2030.We are currently on track at 60 GW of wind installed.
One GW is 1,000 MWOctober 4, 2014
Wind energy is competitive & Texas is a world class leader
Gov. Bush signs Texas RPS goal of 2,000 MW
Texas updates RPS goal of 5,800 MWCREZ Lines initiated

• Wind Turbine Technology:– Rotors continue to increase in size as technology
improves and drives cost down• “GE’s wind unit have now developed a method
for increasing turbine sizes which is akin to a surgical procedure, and involves the dismemberment of existing blades to augment their length via the insertion of custom-manufactured extensions.”

Data from the American Wind Energy Association
Texas leads the nation in installed wind capacity, providing almost 10% of the electricity consumed by Texans, and accounts for over 20% of all U.S. wind generation.

Texas Competitive Renewable Energy Zone (CREZ) Process
In 2005 the Texas Legislature initiated the (CREZ) process in the state which included the requirement to plan electric transmission infrastructure to move electrical energy from renewable resource zones to load centers elsewhere within the state.

• Wind generation output sets ERCOT record March 26, 2014 wind energy output (in
ERCOT) reached a record providing nearly 29 % of the 35,768 MW of electricity being used on the ERCOT grid.

• 85% of Texans believe we should increase the production of renewable energy
• More than 79% of Texans, including 71% of Republicans and 73% of self-identified conservatives, support financial incentives to recruit renewable energy businesses and associated jobs to Texas.

Social and Environmental Issues and AttributesAll forms of electric power production have social and environmental consequences
1. Wind generates power with no emissions
2. Wind is a local resource and does not exclude
other land use, such as crops, livestock, etc.
3. Wind provides significant tax and income revenue
to the local community
4. Wind uses no water to generate powerOctober 4, 2014

Water Use for Power Generation:
• Wind power saved 36.5 billion gallons of water in 2013, according to ACORE’s report. Dubbing wind energy a “drought-resistant cash crop,” farmers and ranchers are receiving consistent income from wind turbines installed on their land.

Energy Employment Comparisons
A 2009 Study at UC Berkeley showed wind energy to be more job intensive per unit of energy produced than other energy technologies.

The business of wind energy:• Wind Power Costs Decrease:• “Now the cheapest means of generating
electricity in many parts of the country, net power generation from wind energy was up 19 percent year-over-year in 2014, meeting 4.13 percent of U.S. grid demand, according to ACORE”
