Biochar is charcoal type created by the pyrolysis of biomass, and differs from ordinary charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture and storage. As much as 12 percent of the world’s human caused greenhouse gas emissions could be sustainably offset by producing biochar. (more…)
Since the Obama Administration came to power in Washington, the EPA has taken upon itself the mission of addressing global climate change. They have been very proactive in getting information out confirming that climate change exists and that it is caused, at least in part, by human activities. Ten petitions were sent to the agency to challenge the EPA’s position (more…)
On Saturday July 31st, the Residential Solar 101 team joined about 150 other volunteers for Grid Alternatives’ Solarthon 2010. In the eight hours we were there, the teams worked to install solar panels on nine different houses in West Oakland. On average, each system was 2 kW in size. A total of 18 Kilowatts (kW) of solar generating capacity was installed (more…)
Restoring damaged rainforest is a more effective way of capturing carbon than cultivating industrial, single-species tree plantations, according to a new study. After testing three types of plantations in northeastern Australia — monoculture plantations of native conifers, mixed plantations, and restored rainforests containing a diversity of trees — Australian (more…)
Yesterday was a great day to be in Colorado. First, I toured a Federal Railroad Administration facility–the work the FRA crew is doing there really deserves its own blog post, so stay tuned for that one next week.
Using lighter colors for rooftops and streets worldwide could help reduce global temperatures and offset the heat from as much as two years of global greenhouse gas emissions, according to a new study. After examining the results from a global land surface model from NASA Goddard Space Flight Center, researchers at the Lawrence Berkeley National Laboratory (more…)
(Reuters) – Democrats in the U.S. Senate aim to debate in late July a bill clamping down on offshore oil drilling practices and fostering more alternative energy use, but no decision has been made on whether to include controversial climate change provisions, aides said on Friday.
As the Gulf of Mexico oil spill entered its 81st day with BP still unable to plug its leaking undersea well, the Senate was planning a two-week debate on an energy and environmental bill that could start as early as July 19. (more…)
The reporting of greenhouse gas emissions by major sources of these pollutants is gaining momentum.
The U.S. Environmental Protection Agency (EPA) is finalizing requirements under its national mandatory greenhouse gas (GHG) reporting program for underground coal mines, industrial wastewater treatment systems, industrial waste landfills and magnesium (more…)
Many energy experts contend natural gas is the ideal fuel as the world makes the transition to renewable energy. But since much of that gas will come from underground shale, potentially at high environmental cost, it would be far better to skip the natural gas phase and move straight to massive deployment of solar and wind power.
For several years, many voices, including Texas energy baron T. Boone Pickens, have been touting natural gas as the best energy source to form a bridge between the current fossil-fuel economy and a renewable energy (more…)
Natural gas will play an increasingly important role in powering the U.S., doubling its share of the energy market from 20 percent to 40 percent within several decades, according to a report from the Massachusetts Institute of Technology. A key reason behind the rise of natural gas is the increasing extraction of gas from underground shale deposits, a controversial practice that poses significant environmental risks. (more…)
