References to climate change almost guarantee funding, even for research topics of little interest beyond academia and eco-activists. Polls reveal that most people worry most about energy and food prices, crime, living standards, Putin’s war on Ukraine, and increasing efforts to control their lives. A recent study by Rutgers University scientists sought to determine how much diversity is required among bee species to sustain wild plant populations. They concluded that ecosystems rely … [Read more...]
Why Can’t Solar Provide Abundant, Affordable Electricity?
Nuclear engineer James H. Rust, over at the Heartland Institute, has just posted a clear, concise, factual piece refuting the claim that there's a "dirty war" to stop expansion of solar energy in the United States. I won't get into the stuff about the "dirty war"---which is entirely bogus, and Rust demonstrates just why---but thought it helpful to pass on just a little of the factual information about why solar has such difficulty competing with nuclear and fossil fuels. Rust writes: In the … [Read more...]
Why Do Taxpayer-Subsidized Businesses So Often Fail?
Subsidize renewable energy? What a great idea! If you like wasting money. SunEdison, which once described itself as the "largest global renewable energy development company" and was America's fastest-growing renewable energy company, filed for bankruptcy April 21. It seems that $1.5 billion combined subsidies and loan guarantees (including $650 million in grants and tax credits---i.e., outright handouts) wasn't enough to make up for the combination of hubris-driven over-expansion, … [Read more...]
How Economically Competitive is “Renewable Energy”?
Condemnation's always most credible when issued by a supporter. That's what the renewable energy sector got from the Lawrence Berkeley National Laboratory's U.S. Renewable Portfolio Standards 2016 Annual Status Report, which states right in its highlights: "More than half of all growth in renewable electricity (RE) generation (60%) and capacity (57%) since 2000 is associated with state RPS requirements." In short, non-hydro renewable energy---wind, solar, geothermal, and biomass---cannot … [Read more...]
Bill Gates Gets It on Wind and Solar
In an interview published in The Atlantic, billionaire Microsoft founder Bill Gates had two very astute observations about wind and solar energy: On the limits of wind power and solar photovoltaic cells: Wind has grown super-fast, on a very subsidized basis. Solar, off a smaller base, has been growing even faster—again on a highly subsidized basis. But it’s absolutely fair to say that even the modest R&D that’s been done, and the various deployment incentives that are there, have worked … [Read more...]
Getting Down to Nitty Gritty: Why Wind and Solar Threaten Electricity Grids and People’s Health and Safety
Rud Istvan has a very instructive article at Judith Curry's Climate Etc. blog about the challenges of bring wind and solar power into use through electricity grids. Bottom line: Their intermittency greatly increases the costs of electricity while reducing its reliability, bringing threats to people's health and safety wherever they begin to make up a significant percentage of total power supplied to the grid. The higher the renewable penetration, the greater this intermittency burden becomes. … [Read more...]
