[Episode #171] – Rejecting Russia

Ever since Russia invaded Ukraine, policymakers and energy professionals alike have been challenged to figure out how Western countries could stop funding Russia’s war machine by halting imports of their fossil fuels. But, considering that Russia is the world’s largest exporter of oil, halting imports is simply not something that can be done quickly.

It is, however, something that must be done as quickly as possible. Numerous proposals and plans have been put forward to outline how various countries could displace the need for Russian energy exports. And generally, those proposals amount to accelerating the energy transition.

In this episode, we delve into some of those proposals and try to understand how much of a role they could play in displacing Russian fossil fuel exports, how long these measures will take, and how the entire global arrangement of trade and political alliances may have to be rearranged to accommodate them.

We tackle this huge topic in a two-hour conversation with three experts. To represent how Europe could proceed, we welcome back to the show Tim Gould of the International Energy Agency (IEA). To represent the UK perspective, we welcome back to the show Simon Evans of Carbon Brief. And to represent the US perspective, we welcome to the show Rachael Grace, Senior Director of Policy at Rewiring America.

[Episode #111] – No Coal in our Christmas Stockings

New energy modeling on the U.S. states of Colorado and Minnesota offers some exciting and even startling insights: It can save everyone money to transition our power generation off of fossil fuels and onto wind, solar, and storage. And moving space and domestic hot water heating onto the power grid by switching to heat pumps, and moving transportation onto the power grid by switching to electric vehicles, will only increase the savings for all consumers—even those who don’t own a car will benefit from transitioning our fleets to EVs. In fact, the more we decarbonize, the more money it will save everyone, the more jobs will be created, and the closer we will get to addressing the climate challenge. Tune into this discussion with energy modeler extraordinaire Christopher Clack for all the exciting details in this special Christmas Day episode.

[Episode #53] – Electrifying Heating

“Deep decarbonization” is all the rage in energy circles, but what does it really mean for actually retrofitting and remodeling buildings? Is it just about replacing oil and gas-fired boilers and furnaces with electric equivalents? Or does it actually mean something far more complex and interesting? Our guest in this episode is a registered engineering technologist in building construction technologies and an award-winning expert on the integration of the building sciences and health sciences who believes the best solutions come from an integrated design approach that takes all elements of buildings and human experience into account, not just how we heat our buildings. This lengthy, wide-ranging, and often humorous discussion covers everything from building science, to regional and national politics, to human physiology and psychology, to the ways that we teach architecture and building design, and much more…and it will leave you with an entirely new concept of what “deep decarbonization” really means. Plus: we finally delve into the arcane but important concepts of exergy and entropy.

[Episode #34] – Transition in the North Sea and Netherlands

The North Seas Countries’ Offshore Grid Initiative would knit together the power grids of the countries adjacent to the North Sea, and enable a far greater share of renewables—especially offshore wind—on the northern European grid than would be possible otherwise. It would also make it possible to use Norway’s substantial hydro capacity as a giant battery to balance out the variability of wind and solar on the grid. And in the longer term, it could be a key part of a European “supergrid” that would connect the transmission grids of all of Europe, and potentially even tap the massive solar capacity of the Middle East and northern Africa. These are big, bold ideas, and implementing them won’t be easy or cheap, but the benefits would be enormous… so much so that building these transmission links might be inevitable. But the planning alone has already gone on for at least seven years, and while some of the countries that would connect to the North Seas Offshore Grid are already building parts of their contribution to it, there is still much work to be done…and building the physical infrastructure might be the easy part! In this episode we talk with a Dutch expert who has been directly involved in evaluating and planning for these supergrids to see where they now stand, what their potential costs and benefits are, and what we might expect in the future.
