Winter and Clean Energy Needs

Large scale electrification of winter heating looks to be essential if the United Kingdom’s legally binding 2050 emissions reduction target is to be met, with other approaches likely playing a lesser role. However, electrification of winter heating poses severe challenges.[read more]

Lessons of the Move from Hybrids Back to SUVs

May 19, 2015 by Steven Cohen

The shift in consumer attitudes from the purchase of hybrid vehicles back to large and gas guzzling SUVs due to the recent drop in gas prices demonstrates that mass behaviors that lead to a sustainable and renewable economy will not come from a simple desire to protect the environment.[read more]

Nonpetroleum Share of Transportation Energy at Highest Level Since 1954

Transportation Energy Share

In the United States, petroleum is by far the most-consumed transportation fuel. But recently the share of fuels other than petroleum for U.S. transportation has increased to its highest level since 1954, a time when the use of coal-fired steam locomotives was declining and automobile use was growing rapidly.[read more]

Solar in the Circular Economy: A New Business Model

May 19, 2015 by Tobias Engelmeier

Solar Economics

Solar is great. It is an abundant, free, and omnipresent source of energy. We just need to convert it into a form of energy we can use: heating, cooling, or electricity. The only problem is that in order to convert it, we need to manufacture specific equipment (collectors, panels, inverters), and that is costly.[read more]

Microgrids, Coast to Coast

Microgrids are getting a lot of attention. Yet how they’re developed could dramatically alter today’s electricity system. At the most obvious level, microgrids could disrupt today’s utilities and their regulated-monopoly business model, because they challenge the centralized paradigm.[read more]

Average Size of New Commercial Buildings in United States Continues to Grow

Batteries and Virtual Storage

Tesla got a lot of attention last week for its new batteries for solar-equipped homes. But there’s an even bigger business opportunity for batteries to help commercial buildings shave peak load, manage demand charges and improve the economics of rooftop solar systems.[read more]

What Tesla's Powerwall Home Energy Storage Battery Means for Texas

Tesla and Texas

There is enough solar energy potential in Texas to power the world twice over. Yet currently we rank 10th in the nation (behind New Jersey) with 330 megawatts (MW), which is enough to power about 57,000 homes. Texas is a state of almost nine million households.[read more]

Friday Energy Facts: Projected Electric Capacity Additions are Below Recent Historical Levels

May 15, 2015 by U.S. EIA: Today in Energy

Electrical Capacity and the Future

Capacity additions through 2017, much of which are under construction, average about 17 GW per year and about half are nonhydro renewable plants (mainly wind and solar) prompted by federal tax incentives and renewable portfolio standards.[read more]

Meanwhile, in Australia: Innovative Storage Quietly Being Installed

Tesla very recently captured the world’s attention with its announcement of a new storage solution recently. What was perhaps most telling for Australians is that the company singled out the land down under as a key market for the future of the technology.[read more]

Is 15% of the Global Clean Energy Market Good Enough?

May 14, 2015 by EDF Energy Exchange

Energy Market Share

How does 15 percent measure up? If you’re talking about America’s share of a $1.3 trillion global clean energy market, that 15-percent figure, while not too shabby, merits further consideration about how we got here – and where we should be heading.[read more]

How EnerNOC Is Building Tesla's Batteries Into Its Demand Response Plans

May 14, 2015 by Jeff St. John

Tesla and Battery Integration

Tesla’s battery business isn’t just about putting Powerwall units into solar-roofed homes. Commercial and industrial customers pay a lot more attention to their energy costs, and they bear a bigger burden from demand charges that batteries are good at containing.[read more]

UK Election and Energy Impacts

After witnessing a political storm around the general election, it is time to start looking at what the Conservatives will be doing to the United Kingdom country over the next five years. This is the first majority Conservative government since 1992 when John Major lead the party.[read more]

Are Apple and Google Disrupting America's Century-Old Energy Market?

May 13, 2015 by EDF Energy Exchange

Tech Companies and Energy Markets

Apple made news earlier this year when it signed an $848-million “direct access” deal to bypass utilities and buy clean energy directly from a solar provider. The deal set a historical precedent for corporate renewable energy purchases that may, over time, have huge financial implications for traditional utilities.[read more]

The German 'Energiewende' - Finally One Step Too Far?

Problems with the German Energy Plan?

In March it was first reported by German TV network ARD that the utility E.ON was considering mothballing one of the most efficient power plants in Europe, a gas-fired high-efficiency combined-cycle gas turbine power plant called ‘Irsching 4 and 5’ in the southern state of Bavaria – which only went online in 2010.[read more]
