"In this real-life model of forest resilience and regeneration, Professor Suzanne Simard shows that all trees in a forest ecosystem are interconnected, with the largest, oldest, "mother trees" serving as hubs. The underground exchange of nutrients increases the survival of younger trees linked into the network of old trees. Amazingly, we find that in a forest, 1+1 equals more than 2"
The cost of wind power in the U.S. is at an all-time low of 2.5 cents per kilowatt hour, according to a new report from the U.S. Department of Energy, and utility companies are in some cases electing to use wind as an energy source over fossil fuels because of its low cost. Although wind power grew modestly in 2013 — installations were only 8 percent of those seen in the record year of 2012 — it now meets 4.5 percent of U.S. energy needs, producing enough electricity to power 16 million homes. The country ranks second only to China in installed wind capacity, the report says, and wind power accounts for 33 percent of all new U.S. electric capacity additions since 2007. That progress has been heavily dependent on federal, state, and local incentives, however, and wind power's growth could slow if those incentives expire. Its viability could also fall if natural gas becomes more affordable than wind, the report cautions.
This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power.
When it becomes apparent that US tight (shale) oil has peaked, there will be a public confidence crisis because the media are parroting the oil and gas industry’s claim that shale oil is an energy revolution and game changer. Indeed, the game will change, but in unexpected ways.
Bottled water is not a significant part of water use compared to agricultural use, but certainly has a heavy footprint in plastic bottles. I believe tap water and well water is pretty safe to drink throughout the US, so what is the appeal??
While millions of youth continue to face challenges and undergo associated psychological impacts, progress is being made. In honor of Youth Day's theme, Mental Health Matters, Julia Gillard reflects on the importance of investing in youth, their futures, and the inclusion of mental health treatment.
One of the REconomy Project’s aims is to find new ways that communities can provide support and investment to local enterprises, who in turn offer benefits back to the community – not just in terms of jobs – but also strengthened local resilience, minimal environmental impacts and fairer ways of trading and profit-sharing.
"We can't do it as an individual, but four hundred communities aggregating and asking for local wind power and solar power — that's really powerful." Oak Park, IL, is one of hundreds of Illinois towns using their authority to buy electricity in bulk on behalf of its residential and s
Hydraulic fracturing is about to move into the Canadian Arctic, with companies exploring the region's rich shale oil deposits. But many indigenous people and conservationists have serious concerns about the impact of fracking in more fragile northern environments.
Called SF RE:MADE, San Francisco-based IwamotoScott Architecture propose up-cycling Candlestick Park and two other out-of-use waterfront landmarks, the Hunters Point Crane and the Islais Creek Silos, providing alternative uses for aging 20th-century structures whose original purposes have become outdated.
It has now been a year since the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has been built and its energy harvesting capabilities began to be monitored. The home was built on the campus at the National Institute of Standards and Technology (NIST), where scientists and researchers conducted a computer simulation that replicated the energy consumption of a family of four. The results showed the home to be a success, since after a ...
