Community Renewables Boom in the U.K.

Written by , on July 24, 2013

A series of government incentives is producing a boom in community renewable energy projects in the U.K. The BBC has reported that there are already more than 2,000 community energy projects across the U.K. According to Andy Deacon of the UK's Energy Saving Trust, "We are already seeing these sorts of schemes popping up on […]  Read more »

Peru Using Solar to Give Electricity to the Poor

Written by , on July 23, 2013

Peru has begun a new program that will use solar panels to provide electricity to more than two million of its poorest citizens. Only two-thirds of the country's population of more than 24 million currently has access to electricity. Energy and Mining Minister, Jorge Merino, says that the program will allow 95% of Peru to […]  Read more »

How to Help Document Power Plants

Written by , on July 10, 2013

Power plants burning fossil fuels contribute over 40% of global carbon dioxide emissions to the atmosphere. But information about where the world’s power plants are located, and how much each one is emitting, is not well-known outside of a handful of industrialised countries. The Ventus Project, led by Dr. Kevin Robert Gurney at Arizona State […]  Read more »

Peak Water

Written by , on June 5, 2013

The US Geological Survey has released a report highlighting the alarming rate of groundwater depletion in the United States. The report says that between 1900 and 2008, the US lost 1,000 cubic kilometers of water from its 40 major aquifers – that's an average rate of 9.2 cubic kilometres a year. Even more alarming is […]  Read more »

However, the U.N. figures are given with a very wide range of uncertainty – between 6.2 billion and 15.8 billion in 2100. A new model developed by a team from the Autonomous University of Madrid (UAM) […]  Read more »

Energy Efficiency of Grid Storage Technologies

Written by , on March 9, 2013

Researchers at Stanford University's Global Climate and Energy Project have published the results of a study of the energy efficiency of different ways of storing energy on the electricity grid. The study found that compressed air and pumped hydro storage are by far the most energy-efficient techniques. Over its lifetime, compressed air storage can store […]  Read more »

Removing Top Predators Can Dramatically Change CO2 Emissions

Written by , on February 18, 2013

When Trisha Atwood of the University of British Columbia studied the effect of removing predator fish from ponds and rivers in Canada and Costa Rica, she found a consistent pattern – carbon dioxide emissions increased more than tenfold after the predators were removed. Wiping out the top predator results in a "trophic cascade" in which […]  Read more »
