Figure 1: Annual share of annual variable renewable power generation in 2014 and in 2030 if all REmap options are implemented

INTERNATIONAL RENEWABLE ENERGY AGENCY
International and national assessments of the global electricity storage market have been hindered by uncertainty
about which technologies and market segments to include. A central question for this roadmap is
whether storage is used to support the integration of renewables or for other purposes.

Guest on The Infra Blog: Tom Kimbis, Vice President of Executive Affairs, Solar Energy Industries Association

Wednesday, June 17th, 2015
Tom Kimbis, SEIA

Tom has been working in renewable energy since 2000, when he began supporting research, analysis, legislative, and planning efforts across all energy efficiency and renewable energy technologies for the U.S. Department of Energy (DOE).

“I’ve seen efficiencies for solar increase over time, and for many years efficiency was talked about as the Holy Grail…what we need right now is not for panels to double their efficiency; what we really need is to have access to cheaper capital, and to eliminate some of the barriers that exist in states and jurisdictions across the country that make it difficult for people to choose solar.”

Figure 1. Renewable energy employment by technology

INTERNATIONAL RENEWABLE ENERGY AGENCY (IRENA)
IRENA estimates that renewable energy employed 7.7 million people, directly or indirectly, around the world in 2014(excluding large hydropower). This is an 18% increase from the number reported last year. In addition, IRENA conducted the first-ever global estimate of large hydropower employment, showing approximately 1.5 million direct jobs in the sector.

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.

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.

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: Technology Promotes Environmental Protection

EPA’s National Enforcement Investigations Center is an environmental forensic center. NEIC scientists work with a variety of technologies to monitor, collect data and analyze pollutants in the environment to better understand the threat to human health and ecosystems. Advanced technologies provide tools for scientists to measure, sometimes in near real-time, pollutants emitted from both large and small sources that can adversely affect entire communities.
