GREEN TECHNOLOGIES:making the difference

GENERATION OF ENERGY FROM THE WAVES

The energy from waves, tides and currents, known collectively as ocean energy, is a massive resource. New systems pump high-pressure water to a power plant, and then the high-pressure water spins the turbines that generate zero carbon electricity.

HARNESSING SOLAR ENERGY

Scientists have designed solar panels that can collect energy from rain and sun. Besides, if it rains, the panels will generate energy from the force of the rain falling on its surface.

VERTICAL GARDENS AND FARMS

Vertical Farming is an eco-friendly technology. If overpopulation continues to be a problem, it will solve food production problems such as providing fresh food to community buildings. They also cut greenhouse gas emissions by eliminating the need to transport.

RECYCLING AND WASTE MANAGEMENT

A new technology allows for household waste to be divided into two groups. One group of plastic fractions can be used for recycling. The other group can be used for fuel or for recycling. Some enzymes dissolve all food and organic waste, until it turns it into a liquid that can be used for biogas.
