UNITED STATES DEPARTMENT OF ENERGY
Today, wind energy provides nearly 5% of the nation’s total electricity generation. With 65 gigawatts (GW) deployed, utility-scale installations in 39 states, and wind power generation exceeding 12% in 11 of those states, wind is a demonstrated clean, affordable electricity resource for the nation. Research and industry experience indicate that wind can be deployed at higher levels while maintaining grid reliability.

Solar Paneled Roadways Vindicated

Sunday, May 17th, 2015

Last year I wrote a piece discussing the possible use of solar panels as road surfaces. In it I discussed a project by engineer Scott Brusaw intended to take our decaying roadways, contributors to climate change, and repurpose them to become part of the solution. Solar power generating roadways, he argued, could virtually eliminate dependence on carbon emitting fossil fuels for decades to come.

Tapping Iowa’s Wind Resources to Reduce CO2 Emissions

Thursday, May 7th, 2015
Of particular interest is the corollation especially observable in the 2010 – 2012 years, between the CO2

IOWA WIND ENERGY ASSOCIATION
In a conservative scenario it is estimated that Iowa wind could easily contribute a reduction of 15 million metric tons of carbon dioxide annually to the region outside of Iowa, and in a more optimistic but still moderate scenario Iowa’s contribution could easily be over 36 million metric tons annually.

De-Carbonizing Power: Figure 1, 2 and 3

BLOOMBERG NEW ENERGY FINANCE
In 2015, the US could set new national records: for annual renewable build; for coal retirements; and for gas burn from the power sector. Meanwhile, electricity-related emissions could fall to their lowest levels since 1994. This Research Note examines our short-term forecasts for US power.

U.S. Homeowners on Clean Energy: A National Survey

Monday, April 13th, 2015
How important is renewable energy to America

CLEAN EDGE
SOLARCITY
In our second annual survey of U.S. homeowner purchasing trends and attitudes, we find that clean-energy products and services – including solar PV, utility-scale renewables, hybrid electric vehicles, and green buildings – continue to experience double-digit compound annual growth rates (CAGRs). Sustained double-digit growth rates for more than a decade reflect the long-term nature of this current shift to more efficient, cleaner, and environmentally friendly products and services. But don’t be mistaken; as our research clearly points out, it is cost savings, much more than environmental factors, that are driving this monumental shift.
