How to Invest in Energy Efficiency to Combat Climate Change

How to Invest in Energy Efficiency to Combat Climate Change | Développement durable et efficacité énergétique | Scoop.it

Energy efficiency is estimated to be a multi-hundred-billion dollar investment opportunity in the U.S., but better policies are required to unlock broad-based financing from institutional investors, who together manage approximately $70 trillion in assets globally.That is the key finding of Power Factor: Institutional Investors’ Policy Priorities Can Bring Energy Efficiency to Scale, a new report issued today by Ceres and its Investor Network on Climate Risk (INCR). Based on the input of nearly 30 institutional investors and other experts from the energy, policy and financial sectors, Power Factor cites three areas of policy—utility regulation, demand-generating policies and innovative financing policies—that can take energy efficiency financing to a scale sufficient to attract significant institutional investment

Stephane Bilodeau's insight:

Investment analysts estimate that climate changecould contribute 10 percent of overall risk within institutional investment portfolios. Furthermore, the International Energy Agency estimates that one-third of emissions reductions must come fromenergy efficiency in order to avoid the worst impacts of climate change. Energy efficiency-related investments thus offer institutional investors an attractive opportunity to manage the risks of climate change while earning returns.

Energy Efficient HVAC Systems Will Surpass $33 Billion in Annual Revenue by 2020, Forecasts Navigant Research | Virtual-Strategy Magazine

Energy Efficient HVAC Systems Will Surpass $33 Billion in Annual Revenue by 2020, Forecasts Navigant Research | Virtual-Strategy Magazine | Développement durable et efficacité énergétique | Scoop.it

Energy consumption by heating, ventilation, and air conditioning (HVAC) systems accounts for roughly 40 percent of total building energy consumption, and in turn, buildings account for 35 percent to 40 percent of total worldwide energy consumption. Thus, HVAC energy consumption in commercial buildings is a key contributor to total global energy consumption. Driven by tightening energy efficiency regulations and by demand for higher-efficiency buildings, the technology for efficient HVAC systems is advancing. According to a new report fromNavigant Research, annual revenue from energy efficient HVAC systems will grow from $17.2 billion in 2013 to $33.2 billion by 2020.


Via ecoInsight
Stephane Bilodeau's insight:

“In the wake of the global recession of 2009, developed markets for efficient HVAC – especially in North America and Europe – remain sluggish,” says Bob Gohn, senior research director with Navigant Research. “However, the North American market will revive during 2013 and begin to experience more substantial growth during 2014. Europe will follow a similar trend, but recovery will likely not occur until mid to late 2014. The strongest region for energy efficient HVAC expansion, however, will be Asia Pacific, which will account for 55 percent of the world market by 2020.”

Via ecoInsight
Stephane Bilodeau's insight:

"First, we found that 25 percent of buildings represent roughly 75 percent of total potential for energy savings. By itself, this insight may not be too surprising. We know that the variation in how buildings are operated, managed, and prioritized for efficiency improvements can vary dramatically. In addition, the large majority of commercial buildings in a given portfolio are small and micro-businesses with low consumption levels and savings potential. The classic 80/20 rule applied to commercial energy efficiency would naturally point to big buildings representing the high end of that 20 percent. But our data revealed a different answer.

 

Second, the biggest buildings don’t necessarily equal biggest savings. In fact, bigger savings may lie in mid-sized buildings. Data indicates that as much as 40 percent of portfolio savings opportunity actually is found in mid-size buildings— greater than the 35 percent found in the largest buildings."

How to make energy efficiency an easy sell

How to make energy efficiency an easy sell | Développement durable et efficacité énergétique | Scoop.it

Energy efficiency is one of the most cost-effective, easy and rapid ways to reduce energy consumption and emissions. Efficiency gains can be measured through software tools, sensor networks and predictive analytics.Yet when you talk to people in the efficiency industry, they invariably complain that people don't pay attention to efficiency measures and tools.

 

 


Via ecoInsight, SustainOurEarth
Stephane Bilodeau's insight:

"Why energy efficiency is a hard sell

The first and most obvious reason is that efficiency is still sold like insurance or vitamins: "You should do it." "It's good for you." "Wouldn't a colonoscopy be worse?" To promote efficiency, vendors need to brush up their sales pitch.

But once you cross the excitement hurdle, you start to see another complaint from customers -- namely, that it remains difficult to prove that efficiency measures work. Historically, efficiency companies have been forced to prove a negative: You saved money, but it's impossible to prove that our measures actually caused the reduction. The number of lawsuits filed against energy service companies in the past year demonstrate that not everyone is happy with the results. Improved auditing tools are helping to ameliorate this problem, but it remains an issue.

Energy efficiency vendors also often gloss over the challenges. "Energy efficiency is not easy," said Marcus Wilcox, CEO of Cascade Energy, which helps industrial and cold storage sites curb power. "It takes a sustained effort."

Another problem? Even for energy-intensive customers, energy is not always a major concern. "It can be a third-, fourth- or even fifth-level concern," Wilcox said."

Forget Energy Efficiency, Think Exergy : Greentech Media

Forget Energy Efficiency, Think Exergy : Greentech Media | Développement durable et efficacité énergétique | Scoop.it
Can a new definition of energy consumption help unlock efficiency?

If we want to understand how to wring more efficiency out of our energy usage, we need to redefine energy use in the first place, argues a new study from the American Council for an Energy-Efficient Economy.

Instead of thinking about energy overall, it is better to think about high-quality energy, or exergy, according to Skip Laitner, a visiting fellow at ACEEE. 

“What most people call energy, for example, is what physicists and engineers are more likely to call exergy, or high-quality energy that is available to do work,” he explains in a blog post. “Energy that is either wasted or useless -- in effect, energy that has no capacity to perform work such as the heat in the atmosphere -- is referred to as anergy.” Add up anergy and exergy and you get total energy. Capture that waste heat, however, and it becomes something useful.

Laitner found that just tracking energy commodities, for instance, accounted for only 80 percent of the exergy necessary to power the U.S. economy in 2010. By measuring and cutting the waste that it takes to complete a task, he argues, there will be greater opportunity for more useful work which can then in turn increase economic activity


Via ecoInsight
Stephane Bilodeau's insight:

"Using those definitions, Laitner found that exergy efficiency has slowed considerably in recent decades, from a 1.4 percent improvement per year from 1950 to 1980, to a 0.4 percent per year growth from 1980 to 2010. The smaller rate of improvement, Laitner argues, weakens the nation’s larger economic productivity. But, if the opposite were to happen -- if the rate of exergy efficiency increased -- the total exergy needed to power the economy could decline even as work continues to grow."

When people talk about “clean energy,” they often mean wind or solar power, and when they’re discussing “energy efficiency" or "energy conservation,” they’re usually talking about doing things like remembering to turn off the lights.

But energy efficiency IS clean energy, just like solar and wind. It’s also cheaper than fossil fuels and doesn’t create pollution. It’s an energy resource that your local utility can help you create by taking simple steps that add up to defeating the behemoth of Dirty Power that’s overheating our planet and fouling our air and water.  It can also save us money on our utility bills!

The barriers to an energy efficiency revolution are high, but not insurmountable.

Americans, thousands of which are still suffering in the dark two weeks after Hurricane Sandy, are painfully aware of how much they rely on electricity – once it goes out.

But for the rest of the year, Americans are still painfully unaware of what drives their home energy bills or what it takes to cut it, according to the eighth annual Energy Pulse survey by Shelton Group, a marketing firm that focuses on the energy efficiency space.

Home energy continues to rise, mostly due to more gadgets and bigger homes, even though appliance efficiencies have improved significantly in recent years. Eighty percent of Americans think they’re using less energy or the same than they used to.
