Wind and Solar Costs Have Risen. How Long Should We Expect This Trend to Last?
And yet, our COALition Government is still working assiduously to hinder any actions that may diminish the profits or ‘harm’ the fossil fuel industry’s continued profligate mining and burning of greenhouse gas emitting carbon-based fuels. By driving continued global warming, these emissions fueling the accelerating climate emergency of droughts, storms, wildfires and rising sea-levels. If the warming is not stopped and reversed we will soon be seeing global famines, economic and social collapses, and mass extinctions (including our own species) as positive feedbacks drive increased greenhouse emissions from soils, burning forests, dying and drying wetlands, and thawing permafrost, plus additional warming enabled by melting polar ice and global ‘dimming’ (where the world absorbs a greater percentage of the solar energy received every day).
We must replace the COALition fossil fuel puppets in our Parliaments with genuine representatives of the people who will work with the economic reality that we must replace greenhouse gas emitting industries with those don’t, and may even engineer effective solutions for recapturing and sequestering some of what was emitted in the past.
Vote Climate One won’t tell you how you should vote. However, we will show you which candidates we think will actively work to help us develop a sustainable future versus those who seem to be indifferent or are actively working to protect their puppet masters in the fossil fuel industry from any changes that might harm their short-term special interests.

Past projections of energy costs have consistently underestimated just how cheap renewable energy would be in the future, as well as the benefits of rolling them out quickly, according to a new report out of the Institute of New Economic Thinking at the University of Oxford.
The report makes predictions about more than 50 technologies such as solar power, offshore wind, and more, and it compares them to a future that still runs on carbon. “It’s not just good news for renewables. It’s good news for the planet,” Matthew Ives, one of the report’s authors and a senior researcher at the Oxford Martin Post-Carbon Transition Programme, told Ars.
The paper used probabilistic cost forecasting methods—taking into account both past data and current and ongoing technological developments in renewables—for its findings. It also used large caches of data from sources such as the International Renewable Energy Agency (IRENA) and Bloomberg. Beyond looking at the cost (represented as dollar per unit of energy production over time), the report also represents its findings in three scenarios: a fast transition to renewables, a slow transition, and no transition at all.
Compared to sticking with fossil fuels, a quick shift to renewables could mean trillions of dollars in savings, even without accounting for things like damages caused by climate change or any co-benefits from the reduced pollution. Even beyond the savings, rolling out renewable energy sources could help the world limit global warming to 1.5º C. According to the report, if solar, wind, and the myriad other green energy tools followed the deployment trends they are projected to see in the next decade, in 25 years the world could potentially see a net-zero energy system.
“The energy transition is also going to save us money. We should be doing it anyway,” Ives said.
The cost for renewable energy has consistently dropped as the world started its transition away from fossil fuels. Solar, for instance, is now cheaper than the creation of new coal or gas-fired power plants, according to an International Energy Agency (IEA) report. However, several reports in the past have suggested that, at some point or another, the falling costs of renewables will begin to level out. For instance, the same IEA report suggests that offshore wind prices will begin to level off now. Advertisement
However, another recent paper reviewed projections for the future of renewable resources and also found that much of the earlier research underestimated future cost reductions in the field. According to Ives, past reports consistently underestimate the technological advancements that are leading to the continued decrease in the price of renewables. Ives’ paper suggests that the models used in these other forecasts have had two problems: they make assumptions about the maximum growth rates of renewables, and they use “floor costs,” a point at which the prices can’t fall further.
Ives’ report focuses mainly on the process of technological advancement, which is part of what has made renewables cheaper. Renewables have routinely performed beyond the expectations of previous papers. “They’ve been getting these forecasts wrong for quite some time,” Ives said. “You can see we’ve consistently broken through those forecasts again and again.”
The Institute of New Economic Thinking report doesn’t place a hard deadline on a cost plateau for renewables. Rather than there being a plateau caused by advancements, Ives said the greater likelihood is that the prices will decrease slower once things like solar and wind end up dominating the market. At that point, technological advances may very well still happen, but they might not be rolled out as frequently as they are now. “It’s the deployment that slows it down,” Ives said.
This largely fits with IRENA’s finding as well, according to Michael Taylor. He’s a senior analyst with the group, which recently released its own report. According to Taylor, the group found that the cost-reduction drivers—improved technology, supply chains, scalability, and manufacturing processes—for solar and wind are likely to continue at least for the next 10 to 15 years. It’s possible that previous forecasts were conservative in their estimations, he said.
“I would expect they’re overly pessimistic,” Taylor told Ars.
However, he noted that some issues might see the reductions slow down. The pandemic, for instance, disrupted global supply chains and made it harder to obtain some essential materials, like the polysilicon used in solar panels. There are also some barriers to fully implementing renewables, such as oil and gas subsidies, public opinion, permitting, etc.
“Just on purely economic grounds, there are increasing benefits to consumers to be had by accelerating the rollout of renewable power generation,” Taylor said. “We’d encourage policy makers to look very seriously at trying to remove the barriers that currently exist.”

We need to elect a government who can actually understand and navigate these issues to fight the climate emergency. The COALition parties and their fellow travelers are puppets of the fossil fuel industry and related special interests. These puppets and charlatans need to be replaced by rational candidates who have committed to put action on the climate emergency at the top of their to-do list if elected. Vote Climate One’s Traffic Light Voting System will give you a lot of information to help you pick the candidate(s) who are most likely to respond to the emergency as you would hope.
