Coal And Water
We recently highlighted how safe drinking water is in short supply. According to research published in the journal Science Advances, at least two thirds of the global population – more than four billion people – live with severe water scarcity for at least one month every year. And 500 million people around the world face water scarcity all year.
Long Island Wind
The Interior Department has recently defined a “Wind Energy Area”, consisting of about 81,000 acres, located 11 miles south of Long Island. The designation is a first step to opening up the acreage for large-scale, competitive wind energy leasing through the Bureau of Ocean Energy Management.
Old-School Companies And Renewable Energy
The biggest Internet companies have been embracing renewable energy for years now. The company that bought the largest amount of clean energy last year was Google, which has three times the renewable capacity of the next biggest user. Other familiar names in the top ten companies in total wind and solar capacity include Amazon, Facebook, Microsoft, and Apple. These companies have been ahead of the pack in looking for sustainable ways to meet their substantial energy needs.

Greener Friendly Skies
In March, United Airlines began using a new biofuel for flights between Los Angeles and San Francisco. The fuel is a renewable product called Honeywell Green Jet Fuel that can replace up to half of the petroleum jet fuel used in flight without any changes to the aircraft technology and it meets all current jet fuel specifications.
Powering Fuel Cells With Wastewater
There are many renewable energy sources to be exploited. Solar and wind power justifiably get the most attention, but they are not the only game in town. There is a growing sustainability movement to capture energy from various kinds of waste, including even the wastewater we flush down the toilet.
River Conservation And Hydropower
Rivers concentrate the water and resources of an entire region. They are literally the lifeblood of much of the world’s fish population. They are also the fuel for hydropower, a critical energy source for human civilization.
Green Steam
Many of the world’s biggest cities have miles of underground pipes built decades ago that provide district energy. District energy systems use a central plant to produce steam, hot water or chilled water that is then piped underground to individual buildings for space heating, domestic hot water heating and air conditioning. As a result, individual buildings served by a district energy system don’t need their own boilers or furnaces, chillers or air conditioners.
Japan’s Hydrogen Future
Japan is a country seeking energy independence as well as environmental credibility. It has grappled with nuclear disaster at Fukushima and is currently the sixth largest emitter of greenhouse gases in the world.
Clean Energy And The Internet
A number of large Internet companies are being very proactive in the area of clean energy. Companies like Google, Facebook, and Apple have invested billions on green energy solutions. This isn’t just good citizenship and good publicity for progressive companies, it is an essential part of the global effort to reduce greenhouse emissions.
Land, Water and Energy
The city of Holtville in California is sometimes called the “Carrot Capital of the World.” This agricultural community has signed an agreement with Australian company Infratech to build a floating solar power system for its water treatment plant.
Community Solar On The Rise
Most Americans are bullish on solar power. However, the majority of Americans are unable to install their own rooftop solar system because either they don’t own the place where they live or because their home is unsuitable for installing solar panels for one reason or another.
Norway And Electric Cars
One of the standard criticisms aimed at electric cars is whether they actually are good for the environment when everything is taken into account. For example, people worry about the amount of energy expended and the environmental impact of actually building the car. Recent studies have shown that this balances out over a relatively short amount of the car’s lifetime.
China And Renewable Energy
When it comes to carbon dioxide, three countries are responsible for half of the world’s emissions into the atmosphere: China, the US, and India. On a per capita basis, we are far worse than China, but its population is so huge that that it produces twice as much CO2 as the United States and nearly one-third of the world’s emissions.
Is Natural Gas Cleaner Than Coal?
The widespread use of hydraulic fracturing (or fracking) as well as improved drilling techniques have created a major boom in natural gas production. This unquestionably has positive economic impacts for many. One of the important consequences of this is that natural gas is increasingly taking the place of coal for powering electrical generating plants.
Businesses Going Solar
The fourth annual Solar Means Business Report is out. It identifies major commercial solar projects and ranks America’s top solar users. Just since the first report came out, the amount of solar power installed by America’s top companies has tripled.
