June 26, 2013 More than 1,300 gigawatts (GW) of wind and solar power generation capacity are expected to come online in the next 10 years, creating an unprecedented amount of instability on the gri…

Duane Tilden‘s insight:

>“Several of the major markets for renewables, including Germany, Japan, and the United States, have enacted rules or legislation encouraging the adoption of energy storage systems for the purpose of integrating variable energy sources onto the grid,” says Anissa Dehamna, senior research analyst with Navigant Research.  “These market incentives come in various forms, including outright subsidies for ESS adoption, reforms that change how variable generation is compensated, and adjustments to connection requirements for variable power plants.”

In particular, changes to the compensation arrangements for variable power generation will have significant influence on the market for ESSs for solar and wind.  Compensation mechanisms have changed drastically over the past 10 years, according to the report, and many compensation schemes have grandfather clauses—meaning that older wind and solar systems have much different compensation rates and structures than newer systems coming online.<

By the end of an upcoming heat wave, we may see a new record for the hottest temperature ever recorded on Earth.

Duane Tilden‘s insight:

>All-time records are likely to be threatened in normally hot places — including Death Valley, Calif., which holds the record for the highest reliably recorded air temperature on Earth at 134°F. That mark was set on July 10, 1913, and with forecast highs between 125°F to 130°F this weekend, that record could be threatened. The last time Death Valley recorded a temperature at or above 130°F was in 1913.

Las Vegas and Phoenix, two cities well-known for their hot and dry summers, are also predicted to approach all-time record territory. Last Vegas’ all-time high temperature record is 117°F and Phoenix’s high is 122°F. Excessive heat warnings are in effect in both cities from Friday through Monday.

Las Vegas could come close to tying its record for the longest stretch of days at or above 110°F, which is 10 straight, set in 1961. Phoenix may approach its record for the number of consecutive days at or above 116°F, which is four, set in 1990. Reliable weather records began there in 1896. Forecast highs in Phoenix range between 115°F to 120°F for Friday through Sunday.<

Safari and other dinotefuran insecticides have been banned by the Oregon Department of Agriculture while the state agency investigates the deaths of an estimated 50,000 insects in Wilsonville and Hillsboro.

Duane Tilden‘s insight:

>[…] Dinotefuran is a member of a type of insecticides called neonicotinoids. Neonicotinoids can be broken down into two groups: the nitro-group and the cyano-group. Dinotefuran is a member of the nitro-group, which has been shown to be more poisonous to pollinators.

The European Union issued a temporarily ban earlier this year on three other nitro-group neonicotinoids, which goes into effect this December.

The Washington state Department of Agriculture decided against banning the ornamental use of neonicotinoids earlier this month. Instead, the Washington department will “urge the U.S. Environmental Protection Agency to consider whether additional use restrictions are needed when the products are applied to ornamental plants.” […]<

Expect more turbulence in world markets

The US Federal Reserve’s hint that it is likely to wind up its quantitative easing programme next year has caused jitters in world markets.

Duane Tilden‘s insight:

>[…] QE {quantitative easing} was in response to lessons learnt from the Great Depression of the 1930s.  That downturn, which lasted a decade, was triggered by liquidity drying up quickly and countries then putting up barriers in a failed attempt to protect their economies.

It’s the kind of collapse that Bernanke, the 14th chairman of the Fed and a scholar of the Depression, was trying to avoid when he chose a course of stimulus. Many doubt QE will be repeated.

The volatility in markets is quite possibly the final stage of Bernanke’s risky experiment to rescue the global economy from the financial crisis, which was sparked by a crisis in US subprime mortgages and the collapse of US investment bank Lehman Bros in September 2008. […]<

Every time energy policy is being discussed, you’ll usually find a call for more R&D spending at the top of the list of ways to solve problems. While I agree that research is great, it’s obviously not enough and, if anything, only the first step.

Duane Tilden‘s insight:

>The result of this comparison doesn’t come as a surprise to anyone who is remotely interested in energy issues. There is a massive energy efficiency gap between the US and other world economies. While this is no surprise to many, it should be a lesson for all those who tell the public that meaningful action requires yet more R&D spending. The 200 million citizens of Japan and Germany are proof that even the technology and the concepts of the past can make a huge difference.<

Green Building Taking Off in Hospitality, Retail Industries

Green building is taking off in the hospitality and retail industries, […]  This year, retail owners that are building green for over half of their projects rose to 38%, up from just 18% in 2011. That’s expected to rise to 52% by 2015.

Duane Tilden‘s insight:

>”Green building has taken such hold in the industry that even sectors with unique challenges, such as retail and hospitality, are making stronger investments,” says Harvey Bernstein, vice president at McGraw Hill Construction. “Clearly the benefits that owners are reporting are key reasons for their green building investments, and as they find better ways to measure those impacts and quantify the value to their sales velocity and to the well-being of their staff, customers and guests, we expect even more rapid engagement in green.”

While lower operating costs are the most frequently reported reason for going green (66% of retailers, 73% of hotels), other factors are also considered very important in their decision-making process:

Utility rebates – Protecting/enhancing brand – just as important as costs for hotels

Improving ROI  […]Energy efficiency is still a key goal, recycling and waste management are also critically important. A strong majority say they require green practices from suppliers, especially on waste handling (75%). <

Utilities fear what they cannot control with community solar – PV-Tech

Posted on by

See on Scoop.it – Green Energy Technologies & Development

Utilities love solar. Or at least they love utility-scale solar, i.e. installations they can own or control through power purchase agreements.

Duane Tilden‘s insight:

>”People like solar and the utility can play a really useful role in bringing solar into a community. But you do have to deal with some issues in terms of how to take advantage of the tax incentives. That can really change the cost of the programme. To take advantage of the tax code, the system has to be located on your property.

[…]

“We’ve seen some prices as low as 5c-6c per kWh once the tax depreciation and tax advantages have been taken by an entity that has that tax appetite. For those who are subscribing this is a resource for the future and many years out that would be a hedge.”

Ultimately, one of the biggest appeals of community solar is the value proposition and that does not always come down to the cheapest rate: communities want power sourced as locally as possible. Green pricing failed to gain mass appeal 10 years ago because consumers were being sold ‘clean power’ generated by wind two states away.<

/PRNewswire/ — The innovative energy efficiency program at the Empire State Building has exceeded guaranteed energy savings for the second year in a row, saving $2.3 million and providing a new model for building retrofits that is now being rolled…

Duane Tilden‘s insight:

>”The success from the Empire State Building retrofit project further demonstrates that thoughtfully applied energy-efficiency investments can deliver unparalleled returns through a combination of lower energy, lower operating costs, and increased building valuation,” said Iain Campbell, vice president, Global Energy and WorkPlace Solutions, Johnson Controls Building Efficiency.  “When implemented under a performance contract, the energy savings are guaranteed, ensuring a no-risk investment and a smart business decision.”

The retrofit has attracted new Empire State Building tenants over the past two years, including LinkedIn, Skanska, LF USA, Coty Inc., the Federal Deposit Insurance Corp., and Shutterstock.  These tenants sought space that reflected their sustainability values, provided more comfort for employees, and allowed them to monitor and control their energy use.

“The Empire State Building project has conclusively proven the business case for deep energy retrofits of any building,” said Raymond Quartararo, international director at Jones Lang LaSalle.  “We have consistently surpassed annual projected energy savings through a process that is very transparent, quantitatively intense and internationally approved.  The overwhelming majority of people want to do their part to reduce energy usage while delivering economic returns and occupying an environmentally responsible building.”<
