What will lighting systems look like in 2020?
According to Greg Merritt, Vice President, Marketing, Lighting at Cree, Inc., "Every lighting solution will be LED, and every lighting solution will offer some type of automated intelligence. More contractors and even distributors will develop their own design and specifying capabilities."

IEA Report Predicts Solar Power Domination by 2050
Two reports released simultaneously last week by the International Energy Agency (IEA) say that by the year 2050, solar power could eclipse fossil fuels, hydro, wind and nuclear as the world’s most widely used source of electricity generation.
Utah, USA -- According to the IEA, solar PV could conceivably be used to generate as much as 16 percent of the world’s electricity needs by mid-century, with solar thermal electricity generated by concentrating solar plants (CSP) accounting for another 11 percent.
The reports state that when combined, PV and CSP could cut annual carbon dioxide emissions by more than 6 billion tonnes – effectively equaling the current output of worldwide transportation emissions and exceeding all CO2 emissions produced in the U.S. today.
According to Technology Roadmap: Solar Photovoltaic Energy, a decrease in the emission of 4 billion tonnes of CO2 per year could occur with worldwide installation of 4,600 GW of PV capacity by 2050. In order for this to occur, total PV capacity will have to reach an average of 124 GW per year, rising to 200 GW per year between 2025 and 2040.
Scott Sklar, chair of the Steering Committee of the Sustainable Energy Coalition and president of The Stella Group, says these targets in PV capacity are entirely within the realm of possibility. “I do think PV can hit these growth levels,” Sklar said, adding that a combination of “reduced loads and storage” – in addition to the use of other renewable energy sources like biomass – will have to be factored into the overall equation to achieve round-the-clock power generation.
By the beginning of 2014, total worldwide PV capacity had surpassed 150 GW and the IEA reports an estimated 100 GW of capacity being installed on a daily basis throughout 2014. “Massive cost reductions” were cited for the exponential growth, which saw more PV capacity installed in the last four years than in the last 40 years combined. The IEA believes the cost of PV will continue to drop, eventually hitting a cost decrease of 65 percent by 2050.
Sklar is also confident PV cost will plunge, if not quite by the margins predicted by the IEA. “Just by the aggregation of purchasing of materials, and scale-up of both module manufacturing and delivery chain, we can reduce costs at least by 50 percent by 2050,” Sklar said. “Possibly more.”
The second report, Technology Roadmap: Solar Thermal Electricity, stresses the inherent abilities of concentrating solar plants (CSP) to store thermal energy and provide necessary backup power on during peak times, on cloudy days, and overnight. Currently, the sum total of global solar thermal deployment is 4 GW – but the report projects with the installation of 1,000 GW of CSP capacity by 2050, 2.1 billion tonnes of CO2 emissions could be eliminated every year.
Additional deployment is expected to occur as a result of developing markets throughout Africa, Australia, China, India, the Middle East, and North and South America.
Frequently looked on as two competing technologies, the IEA sees PV and solar thermal energy ultimately achieving a complementary relationship that will serve to make up for the shortcomings of PV on overcast days and through non-daylight hours.

80' Wind Turbine Install
We are pleased to announce that we are in the process of installing a Bergey Wind Power Turbine that will stand 80' tall at a farm in McHenry County.
Below are some Interesting facts about Wind Energy from the Wind Energy Foundation www.windenergyfoundation.org
Below are some Interesting facts about Wind Energy from the Wind Energy Foundation www.windenergyfoundation.org
Interesting Wind Energy Facts
#1. The United States currently has 61,110 MW of installed wind project capacity, comprising 5.7% of total U.S. installed electric generating capacity.
#2. Wind mills have been in use since 2000 B.C. and were first developed in China and Persia.
#3. Wind power is currently the fastest-growing source of electricity production in the world.
#4. Iowa and South Dakota generated more than 25% of their energy from wind during 2013.
#5. A single wind turbine can power 500 homes.
#6. In 2012, the Shepherds Flat wind project became the largest online wind project in the United States (845 megawatts), breaking the record previously held by the Roscoe Wind Farm (781.5 megawatts).
#7. In 2013, the roughly 168 million megawatt-hours generated by wind energy avoided 95.6 million metric tons of carbon dioxide (CO2) — the equivalent of reducing power-sector CO2 emissions by 4.4% or removing 16.9 million cars from the roads.
#8. There’s enough on-shore wind in America to power the country 10 times over.
#9. In 2013, 12 states accounted for 80% of U.S. wind-generated electricity: Texas, Iowa, California, Oklahoma, Illinois, Kansas, Minnesota, Oregon, Colorado, Washington, North Dakota, and Wyoming. Source: U.S. Energy Information Administration March Electric Power Monthly report.
#10. Most wind turbines (95%) are installed on private land.
#11. Modern wind turbines produce 15 times more electricity than the typical turbine did in 1990.
#12. At times, wind energy produces as much as 25% of the electricity on the Texas power grid.
#13. American wind power is a $10 billion a year industry.
#14. Unlike nearly every other form of energy, wind power uses virtually no water.
#15. By 2030, U.S. wind power will save nearly 30 trillion bottles of water.
#16. At times, wind power produces as much as 45% of the electricity in Spain.
#17. Wind energy became the number-one source of new U.S. electricity-generating capacity for the first time in 2012, providing some 42% of all new generating capacity. In fact, 2012 was a strong year for all renewables, as together they accounted for more than 55% of all new U.S. generating capacity.
#18. During 2013, California led the nation in new wind installations (with 269 megawatts), followed by Kansas, Michigan, Texas, and New York.
#19. 70% of all U.S. Congressional Districts are home to an operating wind project, a wind-related manufacturing facility, or both.
#20. As of May 2014, the United States is home to 46,000 operating wind turbines.
#21. Right now, 559 wind-related manufacturing facilities produce a product for the U.S. wind energy industry across 44 states.
#22. Both Nevada and Puerto Rico added their first utility-scale projects during 2012.
#23. In 2000, more than 60% of U.S. wind power capacity was installed in California, with 17 states hosting utility-scale wind turbines. Today, 39 states and Puerto Rico share 60 gigawatts of utility-scale wind project development.
#24. Wind is a credible source of new electricity generation in the United States. Wind power comprised 43% of all new U.S. electric capacity additions in 2012 and represented $25 billion in new investment. Wind power currently contributes more than 12% of total electricity generation in nine states (with three of these states above 20%), and provides more than 4% of total U.S. electricity supply.

#25. Wind energy prices have dropped since 2009 and now rival previous lows. Lower wind turbine prices and installed project costs, along with improved capacity factors, are enabling aggressive wind power pricing. After topping out at nearly $70/megawatt-hour in 2009, the average levelized long-term price from wind power sales agreements signed in 2011/2012 – many of which were for projects built in 2012 – fell to around $40/megawatt-hour nationwide.
