Some sustainable technologies that could be used by 2050 include:
Renewable energy
Solar and wind power could generate 20% of the world’s electricity by 2050. Solar energy can be generated using solar photovoltaic (PV) and concentrating solar power (CSP) technologies.
Electrification
Switching from fossil fuels to electricity can reduce carbon emissions. For example, companies could transition from petrol and diesel vehicles to electric vehicles.
Sustainable design
Architects and designers could incorporate sustainability into every aspect of their work, such as using green roofs to insulate buildings and absorb rainwater.
3D printing
3D printing could allow goods to be produced on-demand, which could reduce waste and transportation costs.
Smart homes
Smart homes could help optimize energy consumption and reduce carbon footprints.
Autonomous vehicles
Autonomous vehicles could reduce traffic congestion and air pollution.
Sustainable agriculture
Crops could be planted in growing regions where they are most suited to conserve water, fertilizer, and land.
Sustainable workplaces
Air purifiers and proper air filtration of HVAC systems could make the workplace healthier and improve employee productivity.
