Maintaining Mountain Snowpacks Essential for Preserving Valuable Freshwater Resource
Snowcapped mountains generate mountain water runoff and snowmelt, which flow down to streams, rivers, lakes, and oceans. Around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support. Carbon mitigation strategies are needed to maintain snowpack throughout the Americas.

Generating Power at the Point Where Seawater, River Water Meet
It is theoretically possible to generate electricity through the movement of water in locations where seawater and river water meet. This type of technology is called osmotic power generation or blue energy. Though prototypes of this technology have been built, research is still underway to prove that this technology is scalable and reliable.
