By 2050, 90 percent of the world's electricity will be produced

In the Swiss city of Arbedo-Castione, the 70-foot-high crane is still the primary attraction. Big bricks sway from its six arms, but no building is being constructed from these blocks, and no crane is being used to construct the structure. Actually, this crane-shaped iron tower is a storage device for electricity built by Energy Vault, a US-based firm based in Switzerland. To save electricity and return it to the grid, it is driven by 35-tonne gravitational force bricks. When there is a low demand for electricity, the blocks composed of soil-waste material are charged up with the help of AI and additional grid power.

When the demand for electricity rises, the gravitational force pulls these blocks closer to the earth, and the electricity is returned to the grid. This method of electricity conservation may appear to be part of a school science project. This could be critical for a world transitioning to renewable energy. All businesses are under increasing pressure to minimise carbon emissions. This strategy can be useful in a circumstance like this.

Coal creates electricity 24 hours a day, 7 days a week. Wind and solar energy, on the other hand, are affected by the weather and the sun's rays. When the wind stops blowing or when there is a cloud, electricity cannot be generated. As a result, these storage vaults are beneficial in ensuring consistent availability. According to energy research and consulting companies Wood McKenzie and Dan Shreve, lithium-ion batteries are also the solution to this problem. However, they can be used to store energy for a brief period of time.

This is a six-hour storage. There is a scarcity of lithium in this area. As a result, such storage facilities will be required in the future. According to the International Energy Agency, the sun, wind, water, and other renewable energy sources account for 30% of global electricity generation. By 2050, renewable energy will account for 90% of total electricity generation. Switzerland generates 75% of its energy from renewable sources.
