TED: What if buildings created energy instead of consuming it? | Ksenia Petrichenko

The video discusses the role of buildings in energy systems and their potential to aid in decarbonization. It highlights historical building practices, current energy challenges, and the need for energy efficiency, electrification, and decarbonization. The concept of active buildings and smart grids is introduced, emphasizing the importance of policy changes and technological advancements to achieve climate targets.

What is the main reason buildings are considered crucial in efforts to decarbonize the world?

• They are easy to construct.

• They are mostly located in urban areas.

• They are aesthetically pleasing.

• They consume a significant amount of energy.

What percentage of global energy consumption is attributed to buildings?

• 50%

• 33%

• 25%

• 10%

Which of the following is NOT a method to improve energy efficiency in buildings?

• Using better insulation materials

• Increasing the size of buildings

• Upgrading appliances

• Installing energy-efficient windows

Why is there a geopolitical imperative to electrify and decarbonize buildings in Europe?

• To reduce reliance on imported natural gas

• To increase the use of coal

• To promote nuclear energy

• To decrease electricity prices

What is a 'prosumer' in the context of energy systems?

• A building that only consumes energy

• A building that only produces energy

• A building that both consumes and produces energy

• A building that stores energy

What is a major challenge of integrating renewable energy into existing electricity grids?

• Limited availability of wind energy

• Pressure on grid stability

• Lack of skilled labor

• High cost of solar panels

How can electric cars contribute to the energy system?

• By reducing the need for public transport

• By acting as energy storage units

• By consuming more electricity

• By increasing fossil fuel consumption

What is the role of smart grids in future energy systems?

• To manage data and optimize electricity demand

• To replace all existing power plants

• To increase energy consumption

• To eliminate the need for renewable energy

What is a virtual power plant?

• A large centralized power station

• A digital platform managing distributed energy resources

• A new type of nuclear reactor

• A type of renewable energy source

What is a potential benefit of peer-to-peer electricity trading?

• Increased energy prices

• Reduced energy efficiency

• Direct sale of excess energy to other buildings

• Decreased use of renewable energy
