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.

Breeding Dory
The regal blue tang is one of the most common and most popular marine aquarium fish in the world. In the U.S., they have been ranked as high as the 10th most imported fish species out of over 2,000 that enter the country. Apart from aquarium hobbyists, millions of people now associate blue tangs with the character Dory in a couple of popular animated films.
A Solar Airport
Cochin International Airport in southern India is the seventh busiest airport in the country. Its managers were fed up with the facility’s large electric bills and decided to take matters in their own hands.
Hydrogen From The Ocean
Hydrogen is the most abundant element in the universe. Estimates are that it comprises 75% of all matter. There is plenty of it here on earth too, but almost none of it is in its elemental form. It is mostly bound up in compounds like water.
Ebola And Bats
Filoviruses have devastating effects on people and primates, as evidenced by the 2014 Ebola outbreak in West Africa. For nearly 40 years, preventing spillovers has been hampered by an inability to pinpoint which wildlife species harbor and spread the viruses.
Grass-Powered Cars
Several major automakers are betting on hydrogen-powered cars as the future of personal transportation. The first of these cars are already available in California. What isn’t readily available is the hydrogen to power them. There are very few hydrogen stations out there and hydrogen is pretty expensive.
Floating Solar
Installing solar arrays on the surface of bodies of water is an idea that is catching on around the world. Such installations are especially attractive in places like Japan, where land resources are scarce. In the UK, there are a couple of these so-called “floatovoltaic” projects underway – one outside of London and one near Manchester.
Packaging From The Sea
Waste due to excess packaging of the products we buy is a real problem. It is one that most of us are conscious of and more and more businesses are making efforts toward eco-friendly packaging. There is increased use of cardboard, which is recyclable. Most of us try to reduce our waste through recycling. But as we buy more things online and have a growing variety of things delivered to our homes, it is a struggle to receive the things we order in good condition and not end up with piles of packaging materials.
Solar Power In Las Vegas
The Las Vegas Strip has been referred to as an energy consumption nightmare. Just one look at the place provides evidence for the claim: an endless sea of lights, glitz and glamour and cavernous casinos running huge banks of air conditioning equipment in the desert heat. Even with Boulder Dam a hop, skip and jump away, Vegas is struggling to meet its electricity needs.
Cradle-to-Cradle
The circular economy refers to the concept of an economic system in which there is no waste. Materials are recycled, repurposed and reinvented to create new raw materials thereby reducing the need to extract new resources and thus saving money, energy and water resources.
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.
Outdoor Lights Dim Nature
At night our planet is now bathed in artificial light, ranging from streetlights and floodlights to burning gas flares in oil fields. There are few places that are truly dark at night.
Los Angeles’ Giant Battery
Los Angeles has decided to replace a major gas-burning power plant with an energy storage device which, if not exceeded by another before it is completed, will be the world’s largest storage battery.
The Shrinking Ozone Hole
Researchers in Antarctica have been keeping watch on the infamous ozone hole over that continent for several decades. The Montreal Protocol on Substances that Deplete the Ozone Layer was a multinational agreement signed in 1987 designed to reduce the production and consumption of ozone depleting substances that enter the atmosphere. It has been amended in various ways on many occasions over the subsequent years.
Lessons From The Forest
For more than half a century, scientists have converged on Hubbard Brook Experimental Forest in New Hampshire’s White Mountains to explore how forest ecosystems work. The site was established by the U.S. Forest Service to study the relationship between forests and New England’s water supply. In the 1960s, inquiry was expanded to include ecology, biogeochemistry, and studies of birds and other animals.
Geothermal Heating
Geothermal heat pumps use the heat stored in the earth’s surface to heat homes and buildings. Even in the dead of winter, the temperature not very far below ground remains at a temperature typically in the 50s. Geothermal systems tap into this immense thermal resource. Conversely, this same temperature sink can be used to provide cooling during the summer. It takes electricity to run the heat pumps, but is vastly more efficient than using electricity directly to produce heat or to cool air.
The First U.S. Solar Roadway
The first solar roadway in the US will be installed this year at the Historic Route 66 welcome center in Conway, Missouri. The installation will use hexagonal solar panels developed by Idaho-based start-up company Solar Roadways. The initial trial installation will use the panels to cover a sidewalk in the Route 66 center rest area and will only cover a few hundred square feet. The modular building blocks are hexagonal panels of a little less than 5 square feet in area that each generate 48 watts of electrical power.
California Condors
The California condor is the largest North American land bird with a wingspan of about 10 feet. During the 20th century, poaching, habitat loss and lead poisoning reduced the vulture’s population to fewer than two dozen. The U.S. government’s response was to round up every last one of them over a period of 5 years- a total of 27 birds – for a last-ditch captive breeding program. As a result, technically the species became extinct in the wild at that point in 1987. Reintroduction into the wild did not begin until 1991.
Recycled Plastic Lumber
One of the most notable success stories in recycling is that of structural plastic lumber. The material is mostly polyethylene reinforced with stiff plastics or recycled composites. Made from milk containers, coffee cups, and other recycled plastics, structural plastic lumber is lighter than steel, longer-lasting than natural lumber and strong enough to support 120-ton locomotives.
