Description

This lecture covers the Swiss energy transition, focusing on the understanding and selection of energy sources. It discusses the consumption of final energy, indigenous resources, imported resources, the formation of oil and gas, conventional and unconventional reserves worldwide, the European gas pipeline network, and the nuclear fuel cycle. Additionally, it explores the potential of shale gas, the production of nuclear fuel in different countries, and the prospects of thorium as a nuclear fuel. The lecture concludes by highlighting Switzerland's dependence on fossil and nuclear imports, the global resource reserves, the geopolitical challenges, and the controversies surrounding unconventional hydrocarbon resources and uranium mining.

In MOOC

SES Swiss-Energyscope

Switzerland, like many other countries, is revising its energy strategy with a view to a transition towards a more rational use of energy, a more dynamic development of renewable energies and a progressive exit from nuclear energy. In a participatory democracy, such a process can only be based on a good understanding of the basic concepts and the issues related to technological and political choices. This course, which is open to everyone, is aimed at all citizens who wish to gain a better understanding in

Oil and gas reserves and resource quantification

Oil and gas reserves denote discovered quantities of crude oil and natural gas (oil or gas fields) that can be profitably produced/recovered from an approved development. Oil and gas reserves tied to approved operational plans filed on the day of reserves reporting are also sensitive to fluctuating global market pricing. The remaining resource estimates (after the reserves have been accounted) are likely sub-commercial and may still be under appraisal with the potential to be technically recoverable once commercially established.

Thorium fuel cycle

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, , as the fertile material. In the reactor, is transmuted into the fissile artificial uranium isotope which is the nuclear fuel. Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as ), which are insufficient to initiate a nuclear chain reaction. Additional fissile material or another neutron source is necessary to initiate the fuel cycle. In a thorium-fuelled reactor, absorbs neutrons to produce .

Fossil fuel phase-out

Fossil fuel phase-out is the gradual reduction of the use and production of fossil fuels to zero, to reduce deaths and illness from air pollution, limit climate change, and strengthen energy independence. It is part of the ongoing renewable energy transition. Although many countries are shutting down coal-fired power stations, electricity generation is not moving off coal fast enough to meet climate goals. Many countries have set dates to stop selling petrol and diesel cars and trucks, but a timetable to stop burning fossil gas has not yet been agreed.

Fossil fuels lobby

The fossil fuels lobby includes paid representatives of corporations involved in the fossil fuel industry (oil, gas, coal), as well as related industries like chemicals, plastics, aviation and other transportation. Because of their wealth and the importance of energy, transport and chemical industries to local, national and international economies, these lobbies have the capacity and money to attempt to have outsized influence governmental policy.

Thorium-based nuclear power

Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium. A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle—including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production. One advantage of thorium fuel is its low weaponization potential; it is difficult to weaponize the uranium-233/232 and plutonium-238 isotopes that are largely consumed in thorium reactors.
