Will the clean energy transition be cheaper than we thought?

with Dr. Doyne Farmer

The recent working paper by Rupert Way, Matthew Ives, Penny Mealy, and Doyne Farmer, Empirically grounded technology forecasts and the energy transition, suggests that the high estimates of the expense to transition to renewable energy have been inflated, and that it may in fact be cheaper to transition to renewables than to stay on fossil fuels, regardless of the costs of the changing climate. Using probabilistic cost forecasting methods, the authors of the paper project that because of the exponentially decreasing cost curve of renewables like wind and solar, fossil fuels will become nearly obsolete in just 25 years.

Climate Now spoke with co-author of the paper, Dr. Doyne Farmer, to better understand their model and predictions.

Diluting dependence on Russian oil: How renewable energy can defund a war

with Amory Lovins, Co-founder and Chairman Emeritus at RMI

Among the top importers of Russian oil are the EU, Germany, Italy, The Netherlands, and France. The EU accounted for 71% of oil imports from Russia 2 months after the war in Ukraine began. But cutting off oil and gas imports from Russia completely can pose great challenges. The EU is attempting to wean off of Russian oil dependence in response to the invasion of Ukraine by hastening renewable energy adoption. 

The 1970’s oil crises led to a flattening of the exponential demand growth for oil globally. It never recovered thanks to improvements in efficiency. What lessons can we learn from the past as we face the current oil and gas crisis brought on by Putin’s war? Climate Now spoke with Amory Lovins, co-author of a recent RMI article assessing the geopolitical dynamics driving a pivot away from fossil fuels.

Buried treasure: Unearthing the power of the soil carbon bank

with Dr. Asmeret Asefaw Berhe, Professor of Soil Biogeochemistry, University of California, Merced

Soil – that mixture of degraded bedrock, decomposing organic matter, and microorganisms that nourishes the root systems of plants and trees – already holds twice as much CO2 as the earth’s atmosphere and vegetation, combined. And by changing how we manage our soils, we can increase the rate of CO2 trapping from the atmosphere into that soil carbon bank, and in some cases simultaneously enhance the agricultural productivity of a region.

Dr. Asmeret Asefaw Berhe, Professor of Soil Biogeochemistry and Falasco Chair in Earth Sciences at University of California, Merced, is a global leader in the carbon storage potential of soils. She sat down with Climate Now to explain why soils are so good at trapping carbon, how much they could hold, and what we can do to increase soil carbon storage.

Climate risk reporting: Why an SEC mandate makes sense

with Nir Kaissar, Bloomberg Opinion

The U.S. Securities and Exchange Commission wants to standardize climate risk reporting. What does that mean?

On March 21, 2022 the SEC released a proposal for a new rule: that publicly traded companies will have to provide disclosures about how the changing climate will affect their business, and how their business is affecting climate.

This move would formalize a reporting system for climate related-disclosures that investors are increasingly clamoring for. Climate Now sat down with Nir Kaissar, a market economics columnist for Bloomberg Opinion and portfolio manager, to understand what these proposed disclosure requirements entail, how they fit into the scope of the SEC’s mandate, and what the impact of their adoption will be for businesses, investors, policymakers and the public.

Green Transportation: The Power of Electric Vehicles

Electric vs Gas-Powered Emissions

Adopting green transportation and transitioning to a 100% electric fleet requires a momentous cultural, technological, and infrastructure overhaul of the entire global automotive industry. If we are going to undertake such a task, we have to know that it will bring significant results in reducing emissions. So what is the real impact of going electric?

As part of our decarbonizing transportation series, we sat down and did the math. We looked at the net carbon dioxide emissions of an EV over its lifecycle versus lifecycle emissions of a gas-powered vehicle to find out just what the climate benefit of going electric could be.

How the electricity grid works

with Monica Varman

One of the most efficient ways to get to a net-zero economy is to generate electricity from renewable sources, and then make as many things run on electricity as possible.  But, as more end-use services (transportation, heating, industry) are electrified, and the source of electricity transitions from fossil fuels to renewables like solar and wind, the electricity supply chain – the pathway from electricity producers to consumers – will need to evolve, too.

Monica Varman, a climate technology investor at G2 Venture Partners who specializes in investments in grid resilience, joined Climate Now to explain how the electricity sector works and how it is evolving: What is the pathway from creating electricity from a renewable or fossil fuel source, to us being able to flip a switch in our home and have the light come on? And how are companies innovating the electricity generation-transmission-distribution supply chain to prepare us for a carbon-neutral future?

Wind Energy

In order to reach global net-zero emissions by the middle of the century, modeled pathways project that wind energy will need to be a primary source of electricity, accounting for 19-43% of global electricity production.

Today, though, wind produces only 6% of the world’s electricity.

So, what needs to happen to make this level of growth achievable? How can the design, location, and technology of wind turbines be optimized so that wind power reaches its full capacity and costs remain low?

Climate Now spoke with Dr. Simon Watson, Director of the Wind Energy Institute at TU Delft, to understand how we might scale wind power to the degree necessary to keep global warming below 1.5 degrees Celsius.
