Are people really concerned about climate change? What the polls tell us
Are people really concerned about climate change? What the polls tell us A review of recent public opinion polls reveals that the public, when asked only about climate change, will agree overall that it’s a serious problem that demands action. When asked to rank climate change against other concerns, however, it comes well down the […]
El Hierro third quarter 2018 performance update
El Hierro third quarter 2018 performance update In 3Q 2018 Gorona del Viento (GdV) supplied 74.2 % of El Hierro’s electricity (95.4% in July) and 17.1% of its total energy consumption, up from 64.2% % and 14.8% in 2Q 2018. Since project startup in June 2015 GdV has supplied 46.5% of El Hierro’s electricity and […]
Assembly Bill 100 and a 100% renewable California
Assembly Bill 100 and a 100% renewable California The California legislature just passed Assembly Bill 100 (AB100), which according to the inset calls for “100% clean energy by 2045”. The brief review presented in this post shows that AB100, which targets electricity, not energy, will cut California’s greenhouse gas emissions by only about 16% even […]
Batteries, mine production, lithium and the “cobalt crunch”
Batteries, mine production, lithium and the “cobalt crunch” Growth in Li-ion batteries depends on a number of imponderables, such as how rapidly the world converts to electric vehicles, how quickly battery manufacturing capacity can be ramped up and where the electricity to power millions of EVs will come from. This post ignores these issues, concentrating […]
Solar PV potential in Scotland
Solar PV potential in Scotland More than 35,000 homes and 600 businesses in Scotland have installed solar PV panels, but only because of lavish government subsidies. Now that these subsidies are being discontinued the question becomes whether solar PV in Scotland can stand on its own two feet. The data from operating PV arrays presented […]
Have investors lost interest in “clean energy”?
Have investors lost interest in “clean energy”? Before 2011 global investment in clean energy (wind, solar, biomass, biofuels etc.) grew rapidly. Then in and around 2011 many governments abandoned renewables subsidies in favor of capacity auctions, and growth in global clean energy investment ceased. Investment in North and South America has not increased since 2007 […]
Blowout Week 241
Blowout Week 241 This week’s lead story features YouTube, which is fighting what it considers to be the misinformation on videos posted by global warming dissenters with fact-checking boxes (inset), with the data sourced from Wikipedia. We continue with Saudi Arabia’s oil production – is it up or down?; the Saudi/Canada standoff; US LNG and […]
Blowout Week 240
Blowout Week 240 Finally we have an article from a respected academic institution that highlights the prohibitive costs of going renewable with Li-ion battery storage backup. This article has received minimal publicity on the web, so here we give it a little more by making it our feature story. Then on to OPEC; the oil […]
California’s progress, or lack thereof, in cutting its emissions
California’s progress, or lack thereof, in cutting its emissions The California Air Resources Board (CARB) recently published its 2018 inventory of greenhouse gas (GHG) emissions, according to which the state achieved its goal of cutting GHG emissions below 1990 levels in 2016, four years in advance of the 2020 target date*. Gov. Jerry Brown claims […]
The National Infrastructure Commission’s plan for a renewable UK
The National Infrastructure Commission’s plan for a renewable UK The National Infrastructure Commission (NIC) was launched by then-chancellor George Osborne in October 2015 to “think dispassionately and independently about Britain’s long-term infrastructure needs in areas like transport, energy, communication, flood defence and the like.” Well, the NIC has now thought dispassionately and independently about energy […]
RIP the Swansea Bay Tidal Lagoon
RIP the Swansea Bay Tidal Lagoon As expected, the £1.3 billion Swansea Bay tidal lagoon project was finally rejected by the UK government a few days ago. The question, however, is not why the project was rejected, but how it got this far in the first place. As reviewer Charles Hendry saidafter the announcement; “a […]
The BP 2018 Statistical Review, electricity and CO2 emissions
The BP 2018 Statistical Review, electricity and CO2 emissions The just-issued 2018 BP Statistical Review contains a number of variables that were not available in previous reports, in particular electricity generation from oil, gas and coal since 1985. Combining these variables with BP’s nuclear, hydro and renewables generation numbers and with BP’s CO2 emissions data […]
How much of the world’s energy is supplied by renewables?
How much of the world’s energy is supplied by renewables? BP and the International Energy Agency (IEA) measure the contribution of renewables to the global energy mix in terms of primary energy consumed while the World Bank estimates it in terms of final energy consumed. All three give different results, with BP estimating a total […]
Jerry Brown: 3 Billion Will Die from Global Warming
Jerry Brown: 3 Billion Will Die from Global Warming On April 17, 2018, California Governor Jerry Brown delivered a speech at the National Press Club in Washington DC. A day later the headline that forms the title of this post appeared in Google News. I’ve been unable to find out exactly how many views Google […]
The Cook Islands go solar
The Cook Islands go solar Like a number of other remote island communities, The Cook Islands have decided to get rid of expensive diesel power and go to 100% solar within the next few years. To do this they are constructing solar arrays backed up with small amounts of Li-ion battery storage which they believe […]
