Which alternative energy source do you think should be developed in the future. explain

Carbon capture and sequestration

While it's not a power generation technology, carbon capture and sequestration—technologies that allow for the scrubbing of carbon from power plants for storage in underground reservoirs—may finally be coming of age after years of trial and error.

Technology pilot demonstrations at coal-based power plants in places like Australia and the U.S. have sparked new interest in the technology.

The hope is, it could become an enabler for other technologies, such as biomass or algae-based biofuels that produce carbon emissions. That's because organic fuels pull carbon from the atmosphere before converting it to fuel.
