Using renewable energy sources
Electricity can be generated without causing air pollution by using renewable energy sources. Renewable energy sources are naturally replenished and emit little to no greenhouse gases or pollutants into the air. Currently, about 29% of electricity comes from renewable sources, and the cost of these technologies is decreasing, making them the most affordable power sources today.
One way to generate electricity from renewable sources is through wind power. Wind turbines can be used to capture the wind's energy and turn it into electricity. This technology has been criticised for being intermittent, as wind patterns are unpredictable and inconsistent. However, when combined with other renewable sources, wind energy can be a reliable source of power.
Solar power is another renewable energy source that can be used to generate electricity without causing air pollution. Solar panels, or photovoltaic installations, convert sunlight into electricity. Like wind power, solar energy is intermittent, as it relies on access to sunlight. However, when combined with other renewable sources, solar power can be a viable option for meeting electricity demands.
In addition to wind and solar power, there are other renewable sources that can be utilised to generate electricity without causing air pollution. These include hydroelectric power, which uses the force of water to turn turbines and generate electricity, and wave energy systems, which capture the energy from ocean waves.
Furthermore, scientists have recently developed innovative ways to generate electricity from the air itself. Researchers at the University of Massachusetts Amherst have created 'Air-gen', a device that uses a natural protein to create electricity from the humidity and moisture present in the air. This technology is non-polluting, renewable, and low-cost, and it can generate power even in low-humidity areas.
By utilising these renewable energy sources, it is possible to generate electricity without causing air pollution, reducing the impact of electricity generation on the environment and improving public health outcomes.
