Description

This lecture delves into the second part of wind energy, focusing on the search for height and new technologies, the challenges of wind farms, the evolution of wind power in Switzerland and globally, as well as the pros and cons of wind energy. It explores the current and future technologies, emphasizing the race for power and the increase in rotor diameter. The lecture also discusses innovative concepts like Boggawind and the importance of harnessing winds at higher altitudes. It analyzes the power installed annually worldwide and forecasts for the future. Additionally, it examines the current wind energy situation in Switzerland, highlighting priority sites and advantages such as being renewable and having a low ground footprint. The lecture concludes by addressing the development of wind energy globally and in Europe, the limited wind potential in Switzerland, and the need for local political and citizen decisions regarding the visual impact and other drawbacks of wind energy.

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

Wind power

Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid. In 2022, wind supplied over 2000 TWh of electricity, which was over 7% of world electricity and about 2% of world energy.

Renewable energy

Renewable energy is energy from renewable resources that are naturally replenished on a human timescale. Renewable resources include sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy is often used for electricity generation, heating and cooling.

World energy supply and consumption

World energy supply and consumption refers to the global production and consumption of primary energy. Energy can be consumed in various different forms, as processed fuels or electricity, or for various different purposes, like for transportation or electricity generation. Energy production and consumption are an important part of the economy. This topic includes heat, but not energy from food. This article provides a brief overview of energy supply and consumption, using statistics summarized in tables, of the countries and regions that produce and consume the most energy.

Electricity generation

Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage (using, for example, the pumped-storage method). Usable electricity is not freely available in nature, so it must be "produced" (that is, transforming other forms of energy to electricity). Production is carried out in power stations (also called "power plants").

Renewable energy commercialization

Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy.
