The Economics Of Renewable Energy
Very few people are against the use of renewable energy sources like solar and wind power in principle. It is hard to argue against generating power from resources that are free and plentiful. The main knock against renewable power sources has been that they cost too much compared with conventional, fossil-fuel technologies.
Wave Energy In The United States
By some estimates, America’s oceans could provide enough electric power to meet a quarter of the country’s energy needs. Despite this, until recently the contribution to the U.S. electric grid from marine energy has been exactly zero.
Disruptive Light Bulb Technology
Investment companies like to talk about the disruptive nature of technologies and how they change industries while simultaneously changing our lives. The growing emphasis on a low-carbon economy has spotlighted a number of technologies as being disruptive in their industry sectors. One hears this frequently when discussing wind and solar power. Clearly, these two technologies are changing the face of the utility industry, but at least at present, they still represent a fairly small fraction of the overall business.
A Water Superpower
In 2008, Israel was on the verge of catastrophe. A decade-long drought in the Fertile Crescent of the Middle East was scorching the area. Israel’s largest source of fresh water, the Sea of Galilee, had dropped to within inches of the so-called black line at which point irreversible salt infiltration would flood the lake and ruin it forever.
Electric Cars And Climate Change
Electric cars are gradually becoming more popular, but there are still real concerns about their driving range, the availability of charging infrastructure, and their price. Adoption of the technology is still rather slow.
The Carbon XPrize
The Carbon XPrize is a five-year, $20 million competition to identify ways to convert carbon emissions into successful, profitable and useful products. Forty-seven organizations from seven countries are competing for the prizes and include large companies, startups and university researchers.
Solar Power 24/7
The biggest challenge facing both solar and wind power sources is that they don’t produce power around the clock; they only work when the sun is shining or the wind is blowing. As a result, they don’t quite measure up to the requirement for power on demand.
Polystyrene Foam
The San Francisco Board of Supervisors has voted to ban expanded polystyrene, the foam plastic used in food packaging, packing peanuts, coffee cups, and more. It is one of the most extensive bans of this type in the U.S.
A Large-Scale Tidal Energy Plant
Ocean energy is about to take an important step towards making a real impact in Scotland. The MeyGen Tidal Array Project is reaching the final construction of its demonstration phase, which will be the first test of multiple underwater turbines sited together in a full-scale array.
Saving The Sea From Salt
The Persian Gulf along with the Red and Mediterranean seas are getting saltier all the time because of the waste products of desalination. The United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain and Oman account for 45% of the world’s desalination capacity. And the byproduct of desalination is brine, which is twice as salty as seawater. Even advanced desalination plants produce two cubic meters of waste brine for every one cubic meter of clean water.
Testing The Ocean Cleanup Array
It’s no secret that our oceans are full of plastic. Plastic trash can be found on up to 88% of the oceans’ surfaces, with most of the debris concentrated in the top two meters of water. The plastics gather in certain areas of the ocean due to the swirling nature of ocean currents, known as gyres. Some of these concentrations, such as the infamous Great Pacific Garbage Patch, are so large they can be seen from space.
Big Data + Technology = Improved Global Health
Scientists are calling for the creation of a global early warning system for infectious diseases. Such a system would use computer models to tap into environmental, epidemiological, and molecular data – gathering the intelligence needed to forecast where disease risk is high and what actions could prevent outbreaks or contain epidemics.

Hidden Costs of E-Waste
Recycling is often a great thing. But, when you hear about the conditions under which electronic waste is disassembled by impoverished peoples of developing nations, it gives one pause. [Read more…] about Hidden Costs of E-Waste
The Debate Over GMOs
GMO crops have been the source of a great deal of controversy over the years. A major concern has been whether they potentially cause health issues for consumers, which is an understandable worry.
One Million Roofs
Sometime early in May, the United States installed its one millionth solar energy system. Achieving this milestone took the solar industry about 40 years to accomplish. Because of the phenomenal growth of solar power in this country, industry experts predict that it will only take two more years to reach the second million and there are predictions that by the year 2025, there will be one million new installations in the U.S. each year.
