A New Way to Foot Efficiency Upgrades

A New Way to Foot Efficiency Upgrades | Développement durable et efficacité énergétique | Scoop.it
For commercial property owners in California looking to finance energy efficiency upgrades for their buildings, the process should be a bit easier and cheaper come early next year, thanks to a new pilot program approved last week by the state’s Public Utilities Commission.

Based on an “on-bill repayment” feature, the program would allow the property owner to avoid large upfront costs and instead pay for upgrades through regular installments on his utility bill. The idea is that the energy cost savings would cover or exceed the loan or the leasing repayment added to the bill each month. The repayment remains on the property’s utility bill until it’s paid off, even if the property changes ownership, and the utility would have the authority to cut off service for nonpayment.


The concept is not new. About a dozen states offer similar programs. California’s new twist is the source of financing and the obligation to repay the loan regardless of a change in ownership.

Builders aim for super-energy-efficient homes

Builders aim for super-energy-efficient homes | Développement durable et efficacité énergétique | Scoop.it

Crowned with three gables and painted in hues of gray and white, the suburban home in Lake Forest doesn't look much like the domicile of the future.

But as summer heat radiates off the fresh asphalt outside, the home runs comfortably at full tilt indoors. Recessed lights shine, radios blare and air-conditioned splendor greets hot skin. Despite all systems going, the property is producing more electricity than it can consume on a warm summer day — and that's the goal.

Nonprofit hopes to help small biz plug into energy efficiency

While programs to aid and encourage large firms to reduce their energy consumption have been popular and helped to keep electricity consumption in check over the last few years in the state, small businesses have had difficulty accessing the programs due to financial and time constraints, Wrice said.

"You can't keep doing the Pratt & Whitneys of the world," she said. "At some point, you have to target these smaller businesses. Otherwise you're going to have ... boarded up main streets."

CBO | Addressing Market Barriers to Energy Efficiency in Buildings

A large share of total U.S. energy consumption—40 percent—occurs in homes and buildings. Homes and buildings are less energy efficient than they would be if people could assess the value of energy savings more easily and correctly, and if energy prices provided them with stronger incentives to do so. This paper identifies three reasons why people undervalue energy savings: misperceived energy prices, imperfect information about energy efficiency, and biased reasoning about energy savings. The paper then examines four types of policy options for addressing those underlying market imperfections: prices that reflect the social costs of energy use, financial incentives, energy-efficiency standards, and better information about energy efficiency.

In Japan, energy saving takes its toll | Développement durable et efficacité énergétique | Scoop.it

Japan's shutting down its nuclear reactors 'overnight' proves increasingly challenging, as goodwill for draconic energy conservation measures fades. And the shutdown has resulted in massive increased imports of fossil fuels.

The Myth of Affordable Energy

The Myth of Affordable Energy | Développement durable et efficacité énergétique | Scoop.it
Ed Dolan, economist - interview by James Stafford from Oilprice.com

"In my view it is a myth that cheap energy - "affordable energy" as many people like to say is vital to growth. The idea that there is a lockstep relationship between growth of GDP and use of energy is widespread, but the data simply does not bear it out. Instead, what they show is that the world's best-performing economies have become dramatically more energy efficient over time.
(...)
There is only one right way to promote renewables, and that is to introduce full-cost pricing of all forms of energy. Full-cost pricing is a two-part program.

First, it means pricing that covers the full production costs for every form of fuel. No subsidies for anyone—not for oil, not for ethanol, not for wind or solar.

The second half of full-cost pricing is to include all of the nonmarket costs, what economists call the “external costs” or “externalities.” The most publicized of these are pollution costs, whether those take the form of local smog, oil spills, climate change, or bird kills...."

U.S. Energy Efficient Hydropower Upgrades Get More Power from Dams

U.S. Energy Efficient Hydropower Upgrades Get More Power from Dams | Développement durable et efficacité énergétique | Scoop.it

The U.S. has 2,400 hydropower dams, many of which sport out-of-date generating equipment that is, well, generations old. That’s the bad news. The good news is, it all adds up to the potential for a massive energy efficiency upgrade program that could significantly boost U.S. hydropower generation without the monumental expense and environmental disruption involved in new dam construction. In fact, the first round of hydropower upgrades is already underway at an average cost of less than 4 cents per kilowatt-hour.

Why should utilities promote energy efficiency?

Why should utilities promote energy efficiency? | Développement durable et efficacité énergétique | Scoop.it

He acknowledged that there was “an inherent perverse disincentive for utility suppliers to support energy efficiency, since their earnings expand along with increased utilities usage”. Hence, there is a need for suppliers to receive incentives so they could, for instance “take the lead and help an industrial customer retrofit their building to be more energy-efficient, in locations where the customer lacks expertise to do so or faces competing demands for its capital”.

Zero Interest Funds Available for Energy Efficiency

Under this program, eligible projects may be financed at 0% interest. The “loan” is paid back through the customer’s PG&E bill: with the reduced energy savings at least offsetting the loan repayment cost. Once the loan is paid off, the savings are all yours.

“In the time it takes that entire lifecycle to happen for one building, we’re doing 100 buildings, identifying 100 times more opportunities, doing 100 times more engagements,” he said. While that’s not so important to individual building owners, it’s a big deal to a utility that has millions of commercial and industrial customers to sift through, looking for the best targets for efficiency gains.

Gayer & Viscusi: Energy efficiency regulations, the environment, and ...

Gayer & Viscusi: Energy efficiency regulations, the environment, and ... | Développement durable et efficacité énergétique | Scoop.it
Ted Gayer of the Brookings Institution and Kip Viscusi of Vanderbilt University have a new Mercatus working paper that is a careful and thoughtful critique of the rationale, the methodology, and the outcomes of federal energy efficiency regulations. Using standard Pigouvian externality theory, most environmental regulations are based on the “market failure” rationale that individual actions create unaccounted-for and uncompensated costs. Gayer and Viscusi begin their argument with the claim that such a rationale for regulation is indeed valid, to the extent that such costs exist. It also matters whether or not those costs are relevant at the margin — would imposing a tax for a cost or a subsidy for a benefit change the individual’s actions in ways that would account for the externality? If not, then it’s an irrelevant externality.

Energy Efficiency Important to Brand Building

Energy Efficiency Important to Brand Building | Développement durable et efficacité énergétique | Scoop.it
The study, reSources 2012, shows that while 85 percent of companies claim that electricity cost reductions are essential to staying financially competitive, almost as high a proportion – 81 percent – believe they are critical to brand building.  In fact, more than three-quarters of the organizations surveyed say they are actively promoting their energy efficiency efforts to their customers.

Deloitte says that there is now a clear consensus in corporate America that energy efficiency is an important competitive advantage and that senior business leaders are beginning to see it as as a strategic business driver.
