Less waste, fuller plates

Globally, up to 811 million people faced hunger last year, according to the UN Food and Agriculture Organization. At the same time, one-third of food produced worldwide is wasted. Check out McKinsey for Kids and click through the interactive to see how collaborative efforts and tech innovations can help make food security a reality for more hungry families.

Batteries for the grid: A box of sunshine

Solar (and wind) power is essential for a decarbonizing power sector. But it is intermittent. Matching power supply to demand will require more than 300 GW of grid-scale storage, including lithium-ion batteries. Fortunately, projects to build more than 200 GW of battery storage have applied to connect to US grid operators as of the end of 2020, signaling a rapidly growing market.

In some markets, storage capacity would be needed to manage intraday fluctuations in solar generation.
