So implementing energy efficiency measures sounds like a good idea in principle, but how can local authorities or municipalities balance the equation of technology costs and fund the capital expenditure? Put simply, some of the measures that can be implemented deliver savings immediately with payback periods that are very short - in some instances only 6 months. However; to address a set of larger scale measures, the answer comprises 3 elements: i) scale of project, ii) guaranteeing savings through energy performance contracting and iii) access to competitive (low interest rate) finance.

Solar cogeneration combines proven photovoltaic (PV) and solar thermal technologies to maximize total collected energy and optimize economic benefits for institutional, commercial and industrial customers. Using up to 80 percent of the sun's delivered energy
Once of the greatest barriers to the adoption of new clean technologies is the upfront cost, with the resulting sticker shock sending consumers running. Many clean tech firms offer attractive financing packages, but fall down on marketing them effectively, or -- on an even more basic level -- adequately explaining them.
Ultrasonic Systems, Inc. (USI), the leading manufacturer of high-performance ultrasonic spray coating equipment for solar, fuel cell, and semiconductor applications, has been awarded a patent for their CAT ILDS series of nozzle-less ultrasonic spray heads.

The U.S. wind industry is growing again after taking a big step backward last year. Yet turbine makers and wind farm developers are finding few reasons to celebrate as the clean energy source struggles to secure long-term government support while facing stiff competition from cheap natural gas. Once the world's top wind market, the United States ceded that mantle to China last year as a weak economy halted its growth and cut new installations to half of the 10,000 megawatts of capacity built in 2009. Since then, business has picked up, but not for the reasons the industry would like. Energy demand is still tepid due to a gurgling economic recovery, and the low cost of natural gas is keeping power prices low. Pricing in long-term power sales contracts signed by wind developers has fallen 30 percent in the last two years and will fall further this year, according to IHS Emerging Energy Research. Currently, the market is being shepherded by developers who are scrambling to put turbines in the ground ahead of a 2013 expiration of lucrative federal tax credits for wind. Beyond that date, the industry's fortunes are hazy.

InSpec chosen as contractor for new 679-kW solar system using SANYO HIT Solar Panels and a 30-kWh SANYO large-scale lithium-ion rechargeable battery storage system
Boston, Massachusetts (USA) saw the opening of the world's largest large-scale wind turbine blade testing facility this week. The Wind Technology Testing Center—in partnership with the U.S. National Renewable Energy Laboratory—can test blades up to 90 meters long, which is expected to be the industry's largest blade size in coming years. Prior to the facility's opening, domestically produced large-scale wind turbine blades had to be shipped outside of the U.S., usually to Europe, to be tested. The largest predecessors in the U.S. to the Wind Technology Testing Center could only support turbine blades no longer than 50 meters. The facility has the capacity to test up to three blades simultaneously. Standard tests measure fatigue through a four-month endurance process. Two-week-long static strength and resonance testing are also commonplace. The Wind Technology Testing Center itself took roughly two years to build at a cost of just under $40 million. $25 million was awarded by the U.S. Department of Energy as part of the 2009 American Recovery and Reinvestment Act. $13.2 million in additional funds was provided through loans and grants furnished by the Massachusetts Renewable Energy Trust.

Many 1.5 MW wind turbines use traditional open-loop water/glycol cooling systems. Regular water evaporation in the reservoir elevates the mixture's viscosity, prohibiting cooling of the IGBT and associated critical controls, causing the wind turbine to overheat unless serviced, which in turn means turbine downtime and high maintenance costs. Parker's KleenVent Coolant Evaporation Inhibitor (KV-CEI) is a simple add-on to the legacy cooling system, that eliminates water evaporation in the coolant solution and stops the ingress of airborne contaminants, by enclosing the cooling loop. The KVCEI also removes the need for continuous coolant monitoring during the warm season. Traditional maintenance calls to replenish or rebalance the fluids, take the wind turbine and transformer offline, resulting in significant downtime and revenue loss. Parker's cooling system solution optimizes wind turbine uptime and revenue, reduces maintenance costs and increases overall efficiencies.
