    Land requirements are also small: about 10 hectares per gigawatt-hour of storage, [26] which is much smaller than the land occupied by the solar and windfarms that the storage might support. Closed loop (off-river) pumped hydro storage has the smallest carbon emissions [27] per unit of storage of all candidates for large-scale energy storage.

    The total volume of water on Earth is estimated at 1.386 billion km 3 (333 million cubic miles), with 97.5% being salt water and 2.5% being freshwater. Of the freshwater, only 0.3% is in liquid form on the surface. [ 2][ 3][ 4] Because the oceans that cover roughly 70.8% of the area of Earth reflect blue light, Earth appears blue from space ...

  8. Water resources - Wikipedia

    en.wikipedia.org/wiki/Water_resources

    Water resources are natural resources of water that are potentially useful for humans, [ 1] for example as a source of drinking water supply or irrigation water. 97% of the water on Earth is salt water and only three percent is fresh water; slightly over two-thirds of this is frozen in glaciers and polar ice caps. [ 2]

  9. Water in California - Wikipedia

    en.wikipedia.org/wiki/Water_in_California

    Stage 1 water yield within the next seven to ten years is estimated to be 2.9 million acre-feet (3.6 km 3) per year. [103] As part of Stage 1, an Environmental Water Account was established through the purchase of 0.35 million acre-feet (0.43 km 3) of water. The EWA is used to protect fish and other wildlife without reducing water allocations ...
