How to suck carbon dioxide from the sky for fuels and more
7 Jun 2018 at 8:27am
Someday, the gasoline you buy might come from carbon dioxide pulled out of the sky rather than from oil pumped out of the ground. By removing emitted carbon dioxide from the atmosphere and turning it into fresh fuels, engineers have demonstrated a scalable and cost-effective way to make deep cuts in the carbon footprint of transportation with minimal disruption to existing vehicles.
Does living near wind turbines negatively impact human health?
5 Jun 2018 at 8:21am
Wind turbines are a source of clean renewable energy, but some people who live nearby describe the shadow flicker, the audible sounds and the subaudible sound pressure levels as 'annoying.' They claim this nuisance negatively impacts their quality of life.
How Earth slows the solar wind to a gentle breeze
31 May 2018 at 10:11am
A new study describes the first observations of the process of electron heating in Earth's bow shock. The researchers found that when the electrons in the solar wind encounter the bow shock, they momentarily accelerate to such a high speed that the electron stream becomes unstable and breaks down. This breakdown process robs the electrons of their high speed and converts the energy to heat.
Magic in metal could help put excess carbon dioxide to good use
30 May 2018 at 10:29am
A researcher has identified a kind of magic in a metal that may be just what the doctor ordered for Planet Earth. He says the colorful metal, known as bismuth, could help reduce rising carbon dioxide levels in the atmosphere and provide sustainable routes to making fuels.
Top nitrogen researchers imagine world beyond fossil fuels
25 May 2018 at 10:43am
At the invitation of the U.S. Department of Energy's Office of Basic Energy Sciences, 17 top experts in nitrogen research gathered to discuss nitrogen activation chemistry and the field's future.
How greener grids can stay lit
24 May 2018 at 11:15am
Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.
Don't wait for a unicorn: Investing in low-carbon tech now will save money
21 May 2018 at 10:17am
Waiting for a 'unicorn technology' that provides green energy at low cost could be more expensive than adopting low-carbon energy technologies now.
Advanced biofuels can be produced extremely efficiently, confirms industrial ...
21 May 2018 at 10:11am
Researchers have developed new technologies that can be used to convert industrial plants to produce fossil-free heat, electricity, fuel, chemicals and materials. The technical potential is enormous -- using only Sweden's currently existing power plants, renewable fuels equivalent to 10 percent of the world's aviation fuel could be produced.
New catalyst upgrades greenhouse gas into renewable hydrocarbons
17 May 2018 at 11:36am
Engineers have designed a most efficient and stable process for converting climate-warming carbon dioxide into a key chemical building block for plastics -- all powered using renewable electricity.
Can we get 100 percent of our energy from renewable sources?
17 May 2018 at 8:38am
Some researchers doubted the feasibility of many of the recent scenarios for high shares of renewable energy. Now scientists have hit back with their response to the points raised. They demonstrate that there are no roadblocks on the way to a 100 percent renewable future.
European wind energy generation potential in a 1.5 degree C warmer world
16 May 2018 at 7:14pm
The UK and large parts of northern Europe could become windier if global temperatures reach 1.5 degrees C above pre-industrial levels, according to a new study.
A green approach to making ammonia could help feed the world
15 May 2018 at 10:15am
Researchers have developed a new 'green' approach to making ammonia that may help make feeding the rising world population more sustainable.
Carbon-recycling system: Two-electron chemical reactions using light energy, ...
15 May 2018 at 7:57am
Scientists are one step closer to building a carbon-recycling system that can harvest solar energy to efficiently convert CO2 and water into liquid fuels. By optimizing many parts of the system, the researchers say, they can now drive two-electron chemical reactions, a substantial advance over one-electron reactions, which are energy inefficient.
Vulnerable communities may be adversely affected by the transition to cleaner...
7 May 2018 at 12:31pm
Researchers have developed a method for identifying communities that may be negatively affected by clean energy policies that hasten the move from fossil fuels to more environmentally friendly solutions.
Impacts of windfarm construction on harbor porpoises
7 May 2018 at 4:42am
Scientists from Germany, Denmark and the UK have built a model tool to predict what happens to marine animals when exposed to noise from the construction and operation of wind farms at sea.
