Kudzu can release soil carbon, accelerate global warming
Clemson University scientists are shedding new light on how invasion by exotic plant species affects the ability of soil to store greenhouse gases. The research could have far-reaching implications for how ...
Australia carbon tax repeal a 'perfect storm of stupidity'
Australia's axing of its carbon tax and a plan to replace it by offering incentives to polluters to increase their energy efficiency is "the perfect storm of stupidity", scientists and academics argue.
Shocks in the Cygnus Loop supernovae remnant
(Phys.org) —Supernova remnants (SNRs) play a vital role in the lifecycle of dust in the interstellar medium. As shockwaves from supernovae sweep up interstellar material, they heat the gas and dust, and ...
Who gains most from axing the carbon tax – and at what cost?
When the carbon tax was introduced, there was a lot of discussion about winners and losers. The Labor government limited the number of businesses that had to pay the tax, while it also gave carbon tax relief to large carbon emitters and large energy users. There were tax ...
A win-win-win solution for biofuel, climate, and biodiversity
Fossil fuel emissions release billions of tons of carbon into the atmosphere each year, which is changing the climate and threatening the sustainability of life on planet Earth. In Brazil, the demand for ...
Billions of kg of CO2 could be saved by scrapping DVDs, research suggests
A trip down to the local DVD store has slowly become a thing of the past thanks to the rise of video streaming services, which allow viewers to indulge in back-to-back episodes of hit TV series like House ...
Recuperating waste heat under the hood
For his semester project in mechanical engineering, Eliott Guenat studied the best way to recuperate waste heat from a car's engine. The challenge is figuring out how to incorporate the heat exchangers micro-turbomachines.
Bay Area governments make big electric-vehicle buy
A group of San Francisco Bay Area cities, counties and water agencies is joining forces for what is being billed as one of the largest single government purchases of all-electric vehicles in the country.
Wind power cost competitive with natural gas, study finds
(Phys.org) —The costs of using wind energy and natural gas for electricity are virtually equal when accounting for the full private and social costs of each, making wind a competitive energy source for ...
Australia abolishes divisive carbon tax
Australia on Thursday axed a divisive carbon tax after years of vexed political debate, in a move criticised as regressive and out of step with the rest of the world.
Spanish island to be fully powered by wind, water
The smallest and least known of Spain's Canary Islands, El Hierro, is making a splash by becoming the first island in the world fully energy self-sufficient through combined water and wind power.
A biodegradable plastic made from waste methane
What if we could make the Great Pacific Garbage Patch just disappear? What if plastics didn't accumulate in our landfills? What if we could reduce greenhouse gas emissions while replacing up to 30 percent ...
Carbon clean-up needs energy revolution, leaders told
More than two dozen scientific institutes, in unprecedented advice to world leaders, on Tuesday urged major economies to unleash an energy revolution for slashing carbon emissions to safer levels by 2050.
Meeting climate targets may require reducing meat and dairy consumption
Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology, Sweden.
