U.S. Gets Lackluster Energy Efficiency Ranking

U.S. Gets Lackluster Energy Efficiency Ranking

Germany is the global leader in energy efficiency, and the U.S., with its ingrained car culture, is among the least energy efficient of the world’s largest economies. … Read More

Renewables Revolution Could be in Management, Not Tech

Renewables Revolution Could be in Management, Not Tech

Cutting-edge renewable energy technology as a way to tackle climate change may be a sexy topic, but the next 15 years are likely to bring few revolutionary changes in how we generate our electricity. Instead, the revolution is most likely to be in how U.S. power grids are managed and how utilities do business, scientists say.… Read More

U.S. and China Lead the Way on Carbon Capture & Storage

U.S. and China Lead the Way on Carbon Capture & Storage

For years, the energy companies have been telling us not to worry. Yes, mounting carbon emissions threaten to heat up the world – but technology, particularly carbon capture and storage (CCS), will come to the rescue. The trouble is that there’s been plenty of talk about CCS and little action, with few projects being implemented on a large scale.… Read More

Planet is Running a Temp: State of the Climate ‘Check-Up’

Planet is Running a Temp: State of the Climate ‘Check-Up’

Looking at the state of the climate, you can see heat everywhere. From the top of the globe to the depths of the oceans and everywhere in between, the climate is warming and changing in ways humans have never experienced. Last year was between the globe’s third- and sixth-warmest year on record, including record heat in Australia. The frequency of… Read More

Groundwater Is Drought Lifeline for California Farmers

Groundwater Is Drought Lifeline for California Farmers

By the end of this year, the California drought will have cost the state about 3.25 million Olympic-sized swimming pools worth of surface water. That’s 2.15 trillion gallons, or 6.6 million acre-feet of water, lost to drought — enough water to supply 18.4 million average homes with water for an entire year, costing California $2.2 billion in econo… Read More

Summers get hotter, tornado season fizzles, cow manure worsens methane and more. … Read More

Genes Help Plants Handle Rising CO2 Levels

Genes Help Plants Handle Rising CO2 Levels

Biologists in the U.S. have identified the genetic machinery that tells a plant how to respond to more carbon dioxide caused by the burning of fossil fuels. Four genes from three different gene families together control the density of stomata, or breathing pores, on the foliage of the healthy plant. As carbon dioxide levels in the atmosphere rise, … Read More

Measuring Cow & Pig Emissions Goes to New Heights

Measuring Cow & Pig Emissions Goes to New Heights

Methane emissions from cows and pigs had a greater impact on climate change than oil and gas production a decade ago, and livestock emitted more methane than previously expected, according to a new Harvard University study — the first to use high-resolution satellite data to study methane emissions in the U.S.… Read More
