Study Notes

Energy Solutions

Renewable energy is unreliable due to fluctuating natural conditions.
Scientists are developing energy storage solutions, including bricks that store and release power as needed.

Cooling and Heating Solutions

Cooling and heating buildings is a major contributor to environmental problems.
Scientists have developed special fabric for clothing that can regulate body temperature, providing a more efficient solution than cooling entire buildings.
Excess heat generated by factories can be used to provide warmth for businesses, homes, and schools.

Climate Change Mitigation

Planting more trees can help remove CO2 from the atmosphere and mitigate climate change.
The Great Green Wall project across Africa aims to plant a 4,650-mile (7,600 kilometer) wall of trees.
Scientists are researching artificial leaves that can absorb CO2 from the air and convert it into fuel.

Plastic Removal

A machine that creates bubbles at the bottom of rivers can push plastic waste to one side for collection.
This technology could be adapted for ocean cleanup.
Scientists have discovered bacteria that can digest plastic and obtain energy from it, potentially enabling complete plastic recycling.
