James Post asked: WIND ENERGY Bigger windmills mean lower cost per kWh. Therefore the mainstream of the market is 2-3 MW (Mega Watt = 2000-3000 kW peak capacity) windmills. Their average yield is up to 1 MW, depending on wind conditions. However, big systems also bring big problems with them: complexity of installation, accessibility, maintenance. But moreover, they require a …

As more homes in the UK move away from gas heating systems, the need for a sustainable but effective method of heating and providing hot water for the home has become paramount. Heat pumps are rapidly emerging as a lead player in the game of decarbonised energy systems. But they are more than just efficient heaters. When paired with solar …

Agricultural systems are requiring an increasing amount of energy to cope with the current and projected growth in demand. Unfortunately, increased use of nonrenewable energy has a detrimental impact on our environment. In today’s world, where the effects of climate change are very real and fast approaching, it is crucial to use sustainable processes for agriculture. Renewable energy can contribute …

WIND + SOLAR PROVIDE MAJORITY OF NEW GENERATING CAPACITY IN FIRST QUARTER 2017   Washington DC – According to the latest issue of the Federal Energy Regulatory Commission’s (FERC) monthly “Energy Infrastructure Update” (with data through March 31, 2017), wind and solar provided 50.84% of the new electrical generating capacity added to the U.S. grid during the first quarter of 2017. …

By Travis Hoium A decade ago, the solar industry was almost nonexistent in the U.S. There was a large solar thermal power plant in the Mojave Desert that was completed in 1984; but between then and around 2008, there was almost no solar activity in the U.S. That all changed as costs quickly dropped for solar energy, and solar panel prices …

Though the first official assessment that climate change was caused by human activity came in 1988, with NASA scientist James Hansen’s famous testimony to the U.S. Congress, the “carbon neutral” concept, which refers to achieving net zero carbon emissions, is a relatively new one. The non-profit Climate Neutral Network, which developed the Climate Neutral Certification, was incorporated in 1999; the …

Sometimes energy makes headlines, sometimes it doesn’t.  But it almost always has important implications for the global economy, the environment, and our day-to-day lives. Here are 10 energy statistics from 2012 that capture some of the most noteworthy trends of the year, and that will shape the energy world in the years to come. Natural gas, one of the three key fossil …

Mecca, the birthplace of Muhammad, and Islam’s holiest city, has plans to become the first city in Saudi Arabia to run completely on solar power. The Saudi Arabian government has said that it will invest $109 billion to establish a strong solar industry across the nation. The King Abdullah City for Atomic and Renewable Energy program is the jewel in …

U.S. ENERGY POLICY IS “ALL WET” WHEN IT COMES TO HIDDEN COSTS 100,000 Gallons of Water to Produce a Single Megawatt Hour of Electricity? In a Time of Drought and Growing Water Shortages, “Business As Usual” Energy Approach Ignore Huge Water and Other Hidden Costs. Huge demands on increasingly scarce water are a major hidden cost of a “business as …

When power plants begin capturing their carbon emissions to reduce greenhouse gases – and to most in the electric power industry, it’s a question of when, not if – it will be an expensive undertaking. Current technologies would use about one-third of the energy generated by the plants – what’s called “parasitic energy” – and, as a result, substantially drive …

University of Minnesota invention helps advance reliability of alternative energy A University of Minnesota invention could help make storage of solar and wind energy more efficient and economical. The invention was licensed to SustainX, a leading global developer of grid-scale energy storage solutions that use patented isothermal compressed air methods to store large amounts of energy cleanly and economically. “A …
