The Cost of 100% renewables: The Jacobson et al. 2018 Study
The Cost of 100% renewables: The Jacobson et al. 2018 Study Proponents of a global transition to 100% renewable energy point to a number of studies which claim to show that such a transition is feasible, and arguably the most influential of these is the study of Jacobson et al. 2017, an updated 2018 version […]
Wind farm blades damaged after just a few years at sea — hundreds need repair
Wind farm blades damaged after just a few years at sea — hundreds need repair Image of offshore wind farms. Baltic Sea Wikimedia | Mariusz Paździora We are trying to collect dilute erratic energy, spread over hundreds of square kilometers in windy, salty, and wet conditions with machines that spin at 330km/hour. What could possibly […]
Inconvenient energy fact of the day
Inconvenient energy fact of the day In 2016, solar and wind provided just 0.8% of the total world’s energy (Total Primary Energy Demand (TPED)), even after trillions of dollars in taxpayer-extracted subsidies, and will reach only a 3.6% share of energy in 2040, according to the International Energy Agency World Energy Outlook 2017 forecast (see […]
Getting real with renewable energy

Vermont has set a statewide goal of powering 90 percent of its economy with renewable energy by 2050. Many people […]
Battery storage* in perspective – solving 1% of the problem
Battery storage* in perspective – solving 1% of the problem The energy world is fixated on the “huge” amounts of battery storage presently being installed to back up slowly-increasing levels of intermittent renewables generation. The feeling seems to be that as soon as enough batteries are installed to take care of daily supply/demand imbalances we […]
How To Avoid Blackouts Using 100% Renewable Energy
How To Avoid Blackouts Using 100% Renewable Energy Researchers have proposed three different methods for providing consistent power in 139 countries using 100 percent renewable energy. The inconsistencies of power produced by wind, water, and sunlight and the continuously fluctuating demand for energy often hinder renewable energy solutions. In a new paper, which appears in Renewable […]
The Strategy of Maximal Extraction
The Strategy of Maximal Extraction How Donald Trump Plans to Enlist Fossil Fuels in the Struggle for Global Dominance The new U.S. energy policy of the Trump era is, in some ways, the oldest energy policy on Earth. Every great power has sought to mobilize the energy resources at its command, whether those be slaves, […]
EIA estimates for USA in 2050: The Future is Fossil Fuels and Cheap Electricity
EIA estimates for USA in 2050: The Future is Fossil Fuels and Cheap Electricity What energy transformation? The EIA Annual Energy Outlook 2018 is out. The hard heads at the US Dept of Energy crunched the numbers, assumed technology will improve, and modeled the outcomes. According to their best estimates (and even their “worst” estimates) […]

2018: A Breakout Year For Clean Energy
2018: A Breakout Year For Clean Energy The bullish momentum for global clean energy investment, which rose 3 percent to $333.5 billion in 2017, will continue this year. There was significant progress in the transition to cleaner energy in 2017, and 2018 should see more of the same. New solar installations will top 100 GW […]
Can We Afford Renewable Energy?
www.siemens.com Can We Afford Renewable Energy? Over a decade ago we got involved in the development of the biofuels industry in Europe, when it began to take off in earnest there. At that time estimated profits from biodiesel production created considerable enthusiasm, which at one point turned euphoric with new production facilities being announced almost […]
How Chile’s electricity sector can go 100% renewable
How Chile’s electricity sector can go 100% renewable If pumped hydro plants that use the sea as the lower reservoir can be put into large-scale operation Chile would be able to install at least 10 TWh of pumped hydro storage along its northern coast. With it Chile could convert enough intermittent solar into dispatchable form […]
Welcome to renewables world: Australia plans for blackouts, throws billions of dollars, but ABC says it will get “cheaper”
Welcome to renewables world: Australia plans for blackouts, throws billions of dollars, but ABC says it will get “cheaper” The fear is palpable How much fun can you have living in a global experiment? In Australia, peak summer is about to hit in a post-Hazelwood-electricity-grid. We’re drowning in electricity news as summer ramps up. Everyday […]
Transformation glitch? Biggest issue facing South Australia is electricity say 70%
Transformation glitch? Biggest issue facing South Australia is electricity say 70% A Sunday Mail survey (paywalled) shows that despite SA having more “free, cheap and clean” renewable electricity than just about anywhere in the world, the number one biggest issue for most South Australians is … “electricity”. And despite all the renewable jobs created, the […]
Beware the Green Corporate Scam: the 100% Renewable Façade
Beware the Green Corporate Scam: the 100% Renewable Façade A few months ago, Google announced that they will achieve their goal of being 100% powered by renewable energy in 2017 [1]. They are not the only corporation with such lofty goals. Google is joined by GM, Apple, Coca Cola, and more than one hundred companies […]
