Bonneville Dam on the Columbia River, built in the 1930s the 2d giant dam on this western U.S. river, which partially powers Portland and Seattle. Passage for the native and economically important anadromous salmon was an afterthought.
Aerial view of Glen Canyon Dam, blocking the Colorado River above the Grand Canyon and forming Lake Powell — frequently at low water in reduced flow of Colorado River.
Aerial view of the 800 m long Yacyreta dam blocking the Parana River flowing between Argentina (bottom) and Paraguay. The dam, though producing 3100 mw of power, displaced 40,000 people and flooded important habitats.
The small concrete headworks dam on Cheba Chhu for the micro hydro system in Chendebji, Bhutan. Water spins a generator producing about 70 KW of power for 95 households with fewer than 500 people. See http://www.worldviewofglobalwarming.org/himalaya_5/index.php
Rukubji village, an ancient settlement steeped in Bhutanese spiritual history, has had electricity for 20 years since Japan paid for the micro hydro system and turbine which is housed in the building on right. See http://www.worldviewofglobalwarming.org/himalaya_5/index.php
Punatsang Chhu (river), in an agricultural region of Bhutan, is being blocked by a one billion dollar dam project funded and built by India; 85 percent of the electricity will be exported to India. See http://www.worldviewofglobalwarming.org/himalaya_5/index.php
Svartsengi geothermal power plant, iceland, which uses volcanically heated water to spin turbines after which the water feeds the famous Blue Lagoon hot springs resort.
Bathers in the Blue Lagoon, a warm spring associated with Swartsengi Geothermal Power Station, Iceland. Superheated water is vented from the ground near a lava flow and used to run electrical generating turbines, then the water is fed into the lagoon.
Svartsengi geothermal power and heating plant, Iceland. This provides heat and energy for part of Rekjavik and hot water for the Blue Lagoon hot springs and spa.
Bhutan is building two large hydroelectric projects that will block and divert the Punatsang Chhu. Eighty-five percent of the electricity will be exported to India.
Germany’s “energiewende” program of moving to low carbon and non-nuclear electrical power relies on biogas from farm and landfill waste — here in Bavaria where it uses dairly farm manure.
