Protecting our most precious resource: water
California’s ongoing drought serves as a stark reminder that water may well be our most precious resource. Luckily, wind power helps conserve billions of gallons every year. In 2013 alone, wind saved over 35 billion gallons of water. To put that into perspective, that works out to 120 gallons per person, or the equivalent of … Continue reading Protecting our most precious resource: water

Concentrated Solar Power would need to meet 8%-10% of global electricity demand by 2050
The best sites are between 10° and 40°, South or North. As you can see in the chart below, this makes a huge difference, a CSP in Chile might cost half as much as one in Spain. Locating a plant with a solar irradiance of 2,700 kWh/m2 would decrease the generation cost by 25% compared with … Continue reading Concentrated Solar Power would need to meet 8%-10% of global electricity demand by 2050

Lake Turkana Wind Power project
Lake Turkana, in the far northwest of Kenya and extending over the border into Ethiopia, is the world’s largest desert lake, in a region that is central to archaeological investigation into the origin of humanity. It is now also central to two different projects for expanding renewable energy due to come on-line in the … Continue reading Lake Turkana Wind Power project

Water scarcity may be the most underrated resource issue the world is facing today. Seventy percent of world fresh water use is for irrigation. Each day we drink nearly 4 liters of water, but it takes some 2,000 liters of water——to produce the food we consume.1,000 tons of water is used to produce 1 ton … Continue reading Water Resources Fact Sheet

Acciona Agua leads a european R&D project to reduce water treatment costs by 25%
The LIFE-RENEWAT project aims to synchronise waste water treatment plants with the availability of in-plant renewable energy sources integrated to reduce their energy dependence by up to 30%. A reduction of dependence on conventional electricity grids would imply a reduction of a quarter of the cost of treated water. The pilot project is being implemented … Continue reading Acciona Agua leads a european R&D project to reduce water treatment costs by 25%

Rising demand for energy, from biofuels to shale gas, nuclear power, coal and oil, is a threat to freshwater supplies that are already under strain from climate change, the United Nations said in a report on Friday. It urged energy companies to do more to limit the use of water in everything from cooling coal-fired … Continue reading Rising energy demand a threat to water supplies

Solar power toilet minus water
A waterless toilet powered by the sun and developed by American scientists, and a toilet that uses water from air and has been developed by a Kerala-based research company, are among technologies to be unveiled in Delhi later this month. The innovations are among 16 from across the world funded by a Bill and Melinda … Continue reading Solar power toilet minus water

Nuclear, coal and gas plants in Europe use 4.5 billion m³ of water a year, equivalent to that of 82 million EU citizens – the same as the population of Germany – new research shows. Energy production represents 44% of the EU’s total water use: more than any other activity. Yet wind energy, which uses … Continue reading Wind energy, which uses no water, avoids the use of 1.2 billion m³ of water per year

Wind power plays a major role in helping the EU save vast amounts of water used by power stations used to generate energy, a new report claims. The European Wind Energy Association (EWEA) calculated out of all the water used directly and indirectly in the EU, the highest amount (44%) is used in power production … Continue reading Wind energy key to ‘€2.4bn EU water savings’

Wind Power Helps Preserve Water Resources
Energy and water are very closely linked, but those links are often overlooked, according to Stacy Tellinghuisen, Western Resource Advocates’ senior energy and water policy analyst. Tellinghuisen works to promote energy policies that reduce the energy sector’s impact on water resources. Most forms of electricity require water, Tellinghuisen says, and thermal electric power plants use … Continue reading Wind Power Helps Preserve Water Resources

Peak Water: What Happens When the Wells Go Dry?
Peak oil has generated headlines in recent years, but the real threat to our future is peak water. There are substitutes for oil, but not for water. We can produce food without oil, but not without water. We drink on average four liters of water per day, in one form or another, but the food … Continue reading Peak Water: What Happens When the Wells Go Dry?

The fact that wind power and solar energy use virtually no water may become a deciding factor
In a white paper entitled “Water may top the case for renewables,” Mr. Liebreich comments, “The other critical issue missing from the U.S. presidential election battle is water–particularly as U.S. Drought Monitor reports that nearly two-thirds of the nation is now suffering from moderate to exceptional drought conditions. The fact that wind and solar energy … Continue reading The fact that wind power and solar energy use virtually no water may become a deciding factor
