Storing Energy by Gravity
Storing Energy by Gravity – A simple and efficient way for large scale and long duration energy storage. Renewable energy technologies have come a long way since the first solar panels and wind turbines were built to harness the energy from sun and wind to meet the ever increasing energy demands of mankind. Advancements in […]
Renewable Energy Will Not Support Economic Growth
Renewable Energy Will Not Support Economic Growth Container terminal image via shutterstock. Reproduced at Resilience.org with permission. The world needs to end its dependence on fossil fuels as quickly as possible. That’s the only sane response to climate change, and to the economic dilemma of declining oil, coal, and gas resource quality and increasing extraction costs. […]
The Suits Are Flocking to Renewables
The Suits Are Flocking to Renewables Investors like the ‘predictability’ of clean energy. If you’re looking for revolutionaries, radicals and upstart disrupters, you wouldn’t generally search among a crowd of municipal bureaucrats, policy wonks and businesspeople, all suited up for a conference at the Four Seasons Hotel in Vancouver. But the 350-odd delegates to the […]
Are We Witnessing The Beginning Of The End For Fossil Fuels?
Are We Witnessing The Beginning Of The End For Fossil Fuels? Bloomberg recently declared the era of fossil fuels irrevocably in decline: “The world is now adding more capacity for renewable power each year than coal, natural gas, and oil combined. And there’s no going back.” The sea change in how we power our economies officially […]
How Sustainable is Stored Sunlight?
How Sustainable is Stored Sunlight? One of the constraints of solar power is that it is not always available: it is dependent on daylight hours and clear skies. In order to fill these gaps, a storage solution or a backup infrastructure of fossil fuel power plants is required — a factor that is often ignored […]
How Sustainable is PV Solar Power?
How Sustainable is PV Solar Power? Solar photovoltaic (PV) systems generate “free” electricity from sunlight, but manufacturing them is an energy-intensive process. It’s generally assumed that it only takes a few years before solar panels have generated as much energy as it took to make them, resulting in very low greenhouse gas emissions compared to […]
Tesla launches Powerwall home battery with aim to revolutionize energy consumption
Tesla launches Powerwall home battery with aim to revolutionize energy consumption Larger version of battery has been tested in pilot program Tesla CEO Elon Musk is trying to steer his electric car company’s battery technology into homes and businesses as part of an elaborate plan to reshape the power grid with millions of small power […]
Texas Town First Of Many To Switch To 100% Renewable Power
Texas Town First Of Many To Switch To 100% Renewable Power On March 18 the city of Georgetown, Texas announced that it would soon be generating 100 percent of its electricity from renewable sources. Georgetown agreed to purchase the power from a 150-megawatt solar farm that is to be constructed by SunEdison and online in 2016. Coupled […]
2014 biggest year ever for solar, but oil price threat looms
2014 biggest year ever for solar, but oil price threat looms In 2014, record low prices for solar panels fueled a solar boom. The U.S. alone installed 30% more solar photovoltaic capacity than in 2013, making last year the biggest ever for solar PV, according to the 2014 Year-in-Review Solar Market Insight report from GTM Research and the […]
As “Spectacular” Eclipse Covers Europe, Fears Turn To Its Power Grid
As “Spectacular” Eclipse Covers Europe, Fears Turn To Its Power Grid Some parts of Europe witnessed a near total solar eclipse this morning, an event which, while fun to observe (not without the proper equipment please), presents a challenge for solar panels: namely, a lack of sun. As it turns out this same problem happens […]
Electric Utilities Face A Disruptive Future
Electric Utilities Face A Disruptive Future Cheap gas and oil aren’t the only forces disrupting the U.S. electric system. Solar is already wreaking havoc, and large-scale batteries are looming. What Uber and Lyft have done to the taxi industry worldwide is just beginning to happen to the electricity industry; and it could shock consumers – […]
Will New Technologies Give Critical Boost to Solar Power? by Cheryl Katz: Yale Environment 360
Will New Technologies Give Critical Boost to Solar Power? by Cheryl Katz: Yale Environment 360. Today, despite recent progress, solar power accounts for about one percent of the world’s energy mix. Yet the International Energy Agency (IEA) says that solar energy, most of it generated by decentralized “rooftop” photovoltaic systems, could well become the world’s single […]
