If it was up to the liberals of today we would not have the Hoover Dam, The Robert Moses Power plants down river from Niagara Falls or the dams on the Columbia River. All of which provide the least expensive(and cleanest)electricity generated in North America.
This is evidenced by the dams they have been building on the Peace River in Northern BC, Canada. Delays have cost millions of dollars.
Plus they call for removal of the dams on the Snake and other rivers in the Pacific North west
None of these huge projects built in the first half of the 20th century would get approval today because they would find some surrogate species to stop construction.
calif took down the klamath river dams to great distruction of the river for salmon and the fingerligs died..
