Manure To Energy
Dairy cows are very industrious. On average, they produce about 70 pounds of milk a day. Unfortunately, they also produce about 150 pounds a day of manure. Basically, it is an inevitable byproduct of the production of milk.
Floating Solar Panels
Japan is an island country with over 125 million people and doesn’t have much land to spare. The country is largely mountainous and has no room for large-scale solar plants. It has long embraced solar power, but has to be creative about where to put the solar panels.
Food Waste: Now Illegal In Seattle
Previous Earth Wise segments have explored the global problem of food waste. In developing nations, inefficient harvesting and poor storage result in less than half of produced crops making it to the marketplace. In the U.S., food waste tends to occur in grocery stores, homes, and restaurants.
Wind Power In Denmark
Denmark has been a world leader in wind power for a long time. Its wind energy policy had its origins in the 1970s oil crises. The country first embraced nuclear power, but abandoned it in the 80s based on public opposition.
Goats As Allies In Removing Problem Plants
According to the U.S. Department of Agriculture’s last census, there are more than 2.5 million goats living in America. The majority are reared for their milk, meat, and mohair wool. But a small but growing number have been recruited for a new task: combating nuisance and invasive plants.

Algal Biofuel
At the National Renewable Energy Laboratory and at dozens of other labs nationwide, scientists are trying to develop biofuels made from algae. Right now, a gallon of fuel made from algae costs four times as much as a gallon of conventional diesel, but researchers believe that the costs will come down dramatically over time.
Cleaning Up Carbon Pollution And Improving Air Quality
States have a chance to safeguard more than the climate when they adopt the Environmental Protection Agency’s proposed Clean Power Plan. That’s because many of the strategies used to reduce carbon dioxide emissions have the added benefit of improving air quality.

The European Union Can Ban GMO Crops
The widespread use of genetically modified organisms or GMOs in crops is an increasingly controversial practice. Here in the US, there are battles over labeling laws and disclosures about which foods contain GMOs and which ones don’t.
Keeping The Air Clean While Getting Warm
Fireplaces and stoves are coveted features in many homes, providing warmth and ambiance. But managed improperly, these heat sources can be inefficient and unhealthy.
Massachusetts and Solar Power
Massachusetts is not known for its sunny climate and can’t compete with California where huge solar-power farms in the desert can produce hundreds of megawatts of electricity. Nevertheless, the state is enthusiastically embracing solar energy wherever it can.
Flying On Green Energy
If you’ve ever used an online carbon footprint calculator, you may have been surprised by how much of your energy usage comes from air travel. A few flights a year and you’ve produced as much carbon as you have from driving your car all year.
Enhanced Geothermal Systems
Geothermal electricity is a clean, around-the-clock source of power, but has been limited to those few sites where the earth’s heat has created sources of hot water under the ground. Enhanced Geothermal Systems or EGS generate geothermal electricity without the need for natural hot springs or similar hydrothermal resources.
Curbing Curbside E-Waste
These days, technology seems to grow old overnight. In the rush to get the latest gadget, computers, cell phones, and TVs are routinely cast aside. But as of January 1, residents of New York State can no longer put their discarded technology out for curbside pickup. This includes printers, DVD players, video game consoles, electronic keyboards, and older tube TVs.
Microgrids And Energy Resilience
Power outages as a result of extreme weather, excess demand and accidents of various types are on the rise. For many customers, losing electricity is simply not an option. Hospitals, biotechnology research centers that have to maintain cold samples, fire and emergency service centers, and military bases are all examples of facilities that need uninterrupted power. But the conventional power grid simply cannot deliver always-on power.
A New Carbon Sponge
One way to mitigate the effects of burning fossil fuels is to capture the carbon emitted in the process and to prevent it from entering the atmosphere. The most common method in use today at natural gas and coal-burning plants is called amine scrubbing.
Let’s Get The Lead Out!
Lead has long been recognized as a potent neurotoxin associated with cognitive problems. Children who are exposed to lead often have lower IQ scores and behavioral troubles.
Can Organic Crops Be Competitive?
More and more people want to buy organic produce for a number of reasons. There are valid concerns about pesticides, chemical fertilizers, GMO crops, and even the nutritional content in conventional agriculture. Organic farming offers an environmentally sustainable alternative to chemically intensive agriculture. On the other hand, there is a pervasive perception that organic farming simply cannot produce enough food to satisfy the world’s growing appetite.
A Waste-Fueled Bus
The Bath Bus Company in Great Britain recently introduced into its fleet a bus powered by human and food waste. The 40-seater Bio-Bus runs on gas generated through the treatment of sewage and food waste. This fuel is both renewable and sustainable and the new bus helps to improve urban air quality because it produces fewer emissions than traditional diesel engines.
