hydroelectricity
pgleick | March 17, 2015California’s hottest and driest drought in recorded history has shifted the sources of electricity with adverse economic and environmental consequences. The Pacific Institute has just completed and released a report that evaluates how diminished river flows have resulted in less hydroelectricity, more expensive electricity from the combustion of natural gas, and increased production of greenhouse gas emissions.
The current severe drought has many negative consequences. One of them that receives little attention is how the drought has fundamentally changed the way our electricity is produced.…
pgleick | October 18, 2014In a new study just published by the journal Sustainability Science (Springer), analysis from the Pacific Institute (with lead author Dr. Juliet Christian-Smith, now at the Union of Concerned Scientists) shows that many of the fundamental responses of California water users to severe drought actually make the state’s overall water conditions worse – that in the end, many of these actions are “maladaptations.”
Water is a complex resource; and water problems are an equally complex mix of natural resource, technology, social, economic, and political conditions. When water is limited, such as in…
milhayser | August 12, 2013Water may be the most abundant molecule on the surface of the Earth, but more than 99% of it is frozen, underground, or too salty to drink. Only .007% of the planet's water runs in rivers and lakes, yet this precious amount sustains massive populations worldwide. Agricultural societies have long gone to war over water, and as the Earth's population balloons toward 10 billion, global warming destabilizes weather patterns, and pollution sullies what little is left to count on, the conflicts will only get worse. On Significant Figures, Peter Gleick traces Syria's civil war in part to "drought…
