What is Gravity Energy Storage & How It is Work?
Gravity energy storage is a form of mechanical energy storage that uses the earth''s gravity to store energy. The energy is stored in the form of potential energy, which is the energy that an object possesses due to its position relative to other objects. The higher an object is placed, the greater its potential energy.

Waste to Energy – Controversial power generation by incineration
Changes in waste management legislation, such as the phasing out of landfilling, has caused WtE incineration to grow dramatically: in the EU, the quantity of MSW incinerated rose from 32 million tonnes (67 kg per capita) in 1995 to 70 million tonnes (136 kg per capita) in 2018. One cause for this upshot: landfill dumping declined by 56%.
