On a global scale, commercial and residential buildings account for 35 percent to 40 percent of total energy consumption, and while advances in energy-efficient buildings are reducing the energy consumption of many new and existing structures, the spread of zero energy buildings (ZEB)-- which generate as much energy over the course of a year as they use-- is a primary indicator of aggressive approaches to mitigating the impacts of climate change in the built environment, according to Navigant Research.
The Sierra Club is accusing Duke Energy of failing to keep its promises to the State of Indiana in regard to the Edwardsport coal gasification power plant and Duke's claims that the plant would reduce greenhouse gas emissions and protect ratepayers from future carbon regulations.
State Electric Efficiency Regulatory Frameworks reveals that spending and budgets for customer-funded utility electric-efficiency programs continue to grow, driven, in part, by the evolution of state policies that allow utilities to pursue efficiency. In fact, utility company electric efficiency budgets totaled $7 billion in 2013, a 30 percent increase from 2010.
Priorities in energy and sustainability management are shifting, according to an Ecova report that aggregates the findings from a survey of more than 500 C-suite executives, energy and facility managers, and finance and sustainability professionals at U.S.-based companies from a variety of industries. The second annual survey reveals an important shift in the way companies are approaching and viewing energy and sustainability management.
A recent study from Sandia Laboratories pointed to several advantages to storing gaseous hydrogen underground rather than above, particularly if demand for hydrogen fuel-- for fuel cell-powered vehicles, for example-- grows.
If Nebraska wants to sell wind power out of state, it will cost up to $4 billion in transmission line upgrades to do it. That figure is from an analysis the Nebraska Power Review Board issued earlier this week.
Microgrids, at one time thought of as having limited applications, are getting better, cheaper and more sophisticated. Some are in use, typically in a field trial setting. However, the technologies involved are still being tested and enhanced.
The U.S. Department of Energy's (DOE) Advanced Research Projects Agency-Energy (ARPA-E) has made available $60 million in funding for 22 new projects aimed at detecting and measuring methane emissions and developing localized thermal management systems that reduce the energy needed to heat and cool buildings.
With its Horizon 2020 Energy Challenge, the EU is stepping up efforts to ensure its smart cities initiative is a success. The Challenge program will provide funding for local governments in EU and other countries willing to work collaboratively on energy-efficiency improvements, quality of life and more.
Quarterly solar photovoltaic (PV) demand in the Asia-Pacific (APAC) region is expected to reach 10 GW for the first time in the fourth quarter of 2014, according to Solarbuzz, now a part of IHS, Inc., with annual APAC PV demand in 2014 forecast to grow 19 percent over the previous year-- driven mainly by a year-end installation rush in China, as well as strong growth in Japan.
