With all the attention on coal employment, you might think that coal has the biggest share of energy jobs, right? Not by a long shot. Data from United States Energy Employment Report and the Solar Foundation tell a very different story.
A megawatt hour, like it’s little sibling, the kilowatt hour, is a measure of electricity. But just how much is it? How long will it light a bulb? How far can it drive an electric car?
If you want to understand the transition to clean energy, there are three books you need to read. While they aren’t necessarily about clean energy explicitly, they are crucial for understanding the industries that clean energy seeks to upend.
Coal began as dead plants that fell to the bottom of vast swamps millions of years ago. Which countries have the biggest reserves and which burns the most?
From old steamboats to the mines of Appalachia, to World War II, to the oil crisis of 1973, coal has played an easily overlooked but surprisingly foundational role in building America and the world.
If you want to get a visceral sense of how much coal it takes to power our world, you can start by calculating the amount that is required to power a single lightbulb.
How much CO2 and other kinds of pollution would be released if we powered a 100-watt lightbulb for a year using electricity from a coal plant? Let’s dig in.
There are five trends driving the replacement of fossil fuels with clean energy from the sun and wind, and none of them require sweeping new legislation or technology breakthroughs.
Over my 20 years attending TED, there have been a handful of mind-blowing talks on clean, renewable energy. A few of the talks were so powerful, they became catalysts on my own journey into this amazing new industry.
The Freeing Energy team is putting together the definitive list of venture capital and private equity firms investing in clean energy technologies. We need your help.
Taking your house or business entirely off-grid and powering it with clean energy isn’t easy today but these four steps are 100% achievable with current technology. And, before we know it, going off-grid will be as easy as installing a new air conditioner.
The price of solar cells has dropped 300-fold over the last four decades. What is driving this incredible decline and what does it predict for the years to come? Can solar really become the least expensive source of electricity in the long run?
The shift from fossil fuels to clean energy may prove to be the largest and most disruptive energy transition in history. Solar and batteries will unlock the century-old electric monopolies, unleashing a new era of innovation, entrepreneurship and customer choice.
Washington, DC has rediscovered the climate. Democratic rising star, Alexandria Ocasio-Cortez is championing the New Green Deal. We take a look inside this climate manifesto to see what’s really there and whether it can be a blueprint for a clean energy future.
After the 2011 collapse of cleantech investing, the industry is starting to show signs of life once again. Investors are slowly dusting off their checkbooks. This article has four core questions and five parts of the value chain that investors should consider as they fund new cleantech companies.
Cleantech is one of the biggest and most exciting technology industries today. But, despite the buzz, it remains complex and opaque. This article breaks it down into bite-sized chunks and explains how the terms and segments fit together.
Even conservative estimates forecast that transitioning to clean energy will require trillions of dollars of investments. Where will all this money come from? For better or worse, most of it will come from traditional sources like banks and governments. But, even thought it’s relatively smaller, venture capital will play a critical, catalytic role by lowering the risks for every other type of investment.
Clean energy is one of the largest business opportunities in history. But, in 2011, the US venture capital industry lost over $10 billion betting on it. What led to this cleantech collapse? And what did we learn as funding for cleantech is on the rise again?
Nuclear power is the most divisive and debated of all electric generation solutions. Critics say Fukushima and Chernobyl prove it is too dangerous. Supporters say there is no other proven way to generate huge amounts of carbon-free, baseload electricity. So, what is the answer? Should we step up our adoption of nuclear power or shut it down altogether?
I climbed a 250-foot wind turbine to learn firsthand how wind power is changing the landscape of global energy. But it wasn’t until I got to the very top that I embraced the most important truth of wind power – size matters.
