Algae-based fuel is one of many options among the array of possible future energy sources. New University of Virginia research shows that while algae-based transportation fuels produce high energy output with minimal land use, their production could come with significant environmental burdens.
The Ohio State researchers argue that in this case, as forests age, they get rejuvenated with younger individuals of different species – a more-complex and -diverse community will be replacing the old guard.
While roofs across the world sport photovoltaic solar panels to convert sunlight into electricity, a Duke University engineer believes a novel hybrid system can wring even more useful energy out of the sun's rays.
In the hot summer months, it's hard to avoid over-watering your lawn, but saving water is paramount during this time. According to the U.S. Geological Society, about 40 percent of all freshwater is used for irrigation.
New Zealand’s intense ultraviolet light may be bad for the skin, but it could provide a boost for vegetable production, according to new research by a Massey University crop scientist.
New computer modeling work shows that by 2100, if society wants to limit carbon dioxide in the atmosphere to less than 40 percent higher than it is today, the lowest cost option is to use every available means of reducing emissions.
Ensuring that a population of fish is breeding naturally within their holding pens is a sustainable fish farming goal.
Writing in the journal Annals of Botany, Professor Douglas Kell argues that developing crops that produce roots more deeply in the ground could harvest more carbon from the air, and make crops more drought resistant, while dramatically reducing carbon levels.
To date, many academics and government officials have argued that putting a price on carbon – most commonly through taxes or emissions trading – is all that is needed to overcome every possible barrier to delivering cost-effective energy efficiency improvements.
Rice – which provides nearly half the daily calories for the world’s population – could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, U.S. Geological Survey-led research shows.
Carbon dioxide still plays a major role in climate change, but other greenhouse gases contribute to the problem.
The Department of Energy's L Prize challenged the lighting industry to develop high-performance, energy-saving replacements for conventional light bulbs that will save American consumers and businesses money.
While water scarcity presents a global crisis, one software-as-a-service company is using technology to reduce water loss through faulty infrastructures.

Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction.
Summer is the ideal season for vacations, and whether you plan to spend your days beach bumming, hiking with friends or visiting out-of-town relatives, these tips will help reduce your at-home energy consumption as much as possible while you are away.
The biggest hurdle to widespread implementation of solar power is the fact that the sun doesn't shine constantly in any given place, so backup power systems are needed for nights and cloudy days. But a novel system designed by researchers at MIT could finally overcome that problem, delivering steady power 24/7.
Researchers in the Pacific Northwest have developed a new catalyst material that could replace chemicals currently derived from petroleum and be the basis for more environmentally friendly products, including octane-boosting gas and fuel additives, bio-based rubber for tires and a safer solvent for the chemicals industry.
The agave plant has not yet been widely cultivated as a fuel source, but it promises some significant advantages over existing sources of ethanol such as sugarcane and corn.
Communicating the benefits of a business solution to various stakeholders requires wearing multiple hats and re-focusing the conversation to the elements that are important to the individual.

The facility will allow researchers and manufacturers to test buildings systems and components under real-world conditions by swapping out systems and changing configurations and then allow rigorous monitoring of performance of every key building element that impacts energy consumption.
