It’s been 60 years in the making and it’s finally here: America’s power generation fleet has changed so much since the 1950s, and especially over the last decade, that the amount of carbon we emit per megawatt-hour of electricity produced has dropped to its lowest point in recorded history.
In fact, 2015 could be the cleanest ever for our power industry, according to a recent report by Bloomberg New Energy Finance. Two major developments have driven this change:
- Renewable energy projects are skyrocketing.
Based on confirmed contracts, renewable energy will hit a record 18.3 gigawatt of new build in 2015. Of that, 9.1 gigawatts will come from solar (an all-time high) and 8.9 gigawatt from wind (third-most ever).
By the end of 2014, renewables (not including hydro power) accounted for 7 percent of electricity generated in the United States. Solar and wind, alone, are expected to account for 60 percent of new capacity in 2015. Read More
Imagine you’re trying to lose weight. If you step on the scale once a month, how can you possibly know how each of your daily decisions affects the number? Weighing yourself every day would be a step up, giving you a much clearer picture of the effects of each day’s choices. Now imagine the potential results if you could access real-time data – if you were able to see just how many calories were in each food you picked up, as well how much energy you were exerting at any given moment.
Thanks to a meta-analysis on behalf of the American Council for an Energy Efficiency Economy (ACEEE), we can now see that access to this kind of granular, real-time data on electricity use leads to significant household electricity savings.
Survey highlights importance of timeliness and granularity
The ACEEE survey aggregates multiple studies designed to evaluate the effectiveness of different types of electricity customer feedback from the past 20 years, including 61 trials from around the world: 33 from the U.S., 13 from Europe, 9 from Canada, and 3 others. Such a diverse pool allows us to draw important conclusions about consumer energy use habits while controlling for variations in culture, climate, and energy use patterns. The results are displayed in the graph below. Read More
If there is one thing that works in the world of advocacy, it is a ratings table that shows how one state, metropolitan area, or utility compares to its peers. The latest report, U.S. Clean Tech Leadership Index, from Clean Edge does just that.
The fifth annual U.S. Clean Tech Leadership Index finds that California, Massachusetts, Oregon, Colorado, and New York lead the way among states in solar and electric vehicle adoption, with smart climate policies and clean energy financing driving the clean tech leadership index growth.
Clean energy is becoming a popular choice for mainstream America with 11 states now generating more than ten percent of their electricity from non-hydro renewable sources, according to the Clean Edge report. As seen in the graph below, Iowa leads the way in utility-scale wind, solar, and geothermal electricity generation. Read More

The use of rechargeable batteries – in everything from iPhones, TV remotes, and even cars – has become pervasive over the past few years, especially as they have become more affordable. So why can’t we use them to help power our homes and businesses, too? The idea isn’t that complicated. But the cost of large-scale energy storage is still prohibitively high.
However, in select markets, like Hawaii’s commercial building market, privately connected battery storage is already cheap enough, compared to utility rates, to warrant installation. Furthermore, other energy storage markets, like California and New York, could reach the point of commercial viability in the next ten years – and not just for commercial buildings, but the residential market, too.
