Solar and hydropower are two pillars of the global renewable energy mix, but their true potential emerges when they work together. ...
Understanding the relationship between alkalinity and algae growth is essential for those managing drinking water reservoirs, cooling lakes, hydropower dams, and industrial water bodies. These are critical resources where persistent algal blooms not only affect ecosystems but also impact water safety, infrastructure, and ...
Mountainous regions present unique challenges for construction projects, requiring specialized equipment to ensure efficiency, safety, and cost-effectiveness. One of the most versatile machines for such environments is the self-loading concrete mixer, which combines the functions of a loader, mixer, and transporter in one compact unit. Its mobility and independence from external batching plants ...
E-Tech has played multiple roles in Ecuador. Since 2010 we have worked for the most part on large-scale mining, as it was planned and then developed on indigenous territory, and have attempted to change the course of its development. We have provided assistance as an environmental/technical NGO and as visiting faculty at Ecuador’s Escuela Politecnica Nacional. E-Tech has focused on the ...
Located in upstate NY, this hydroelectric plant was built in the mid-1980s in response to the federal PURPA legislation. The site is well suited to hydropower, with a small labyrinth dam spanning the river banks just above a beautiful cascade into a deep gorge. ...
What is Dissolved Oxygen? Dissolved oxygen is a measure of how many O2 molecules are present in a liquid (most often water) at any given time. It is incredibly important because oxygen sustains life in bodies of water and reduced dissolved oxygen levels can act as a warning for events that destroy ecosystems, such as algae blooms. The units of measurement are typically mg/L or on a scale of ...
Water levels in Lake Mead, which supplies 90% of Las Vegas’ drinking water, are at their lowest since the Hoover Dam was built to create the reservoir in the 1930s. Hydropower generation at the dam has dropped, and the water-level “bathtub rings” hundreds of feet up the canyon walls are stark reminders of the drought. ...
Spencer Dam was a dam constructed for hydropower in 1927 on the Niobrara River in northern Nebraska. ...
According to TheClimateGroup.org, the transportation sector is the fastest-growing contributor to climate change, accounting for 23% of global energy-related greenhouse gas (GHG) emissions. Efforts to achieve carbon neutrality are everywhere you look. Between countries announcing ambitious goals for the next decade, and some of the world’s largest companies (including Ikea, Daimler, ...
The UN demands urgent action on biodiversity. Sustainable hydropower can be part of the solution, writes Alain Kilajian of the International Hydropower Association ...
Longer periods of seawater intrusion in the river’s delta system threatens a collapse of Vietnam’s food chain The countless boats, houses, and markets on the Mekong River delta’s complex lattice of streams, rivers, and canals are home to millions of inhabitants, who all depend on the health of the delta. The 65,000-km2 region sustains 60% of Vietnam’s population and is ...
The United States Bureau of Reclamation’s Underwater Investigations Dive Team (an agency of the U.S. Department of the Interior) is responsible for all underwater investigation for the Bureau’s hydroelectric dams. Under pressure to work faster, safer, and more efficiently, they investigated ROV technology to replace human diving when possible. Unlike human divers, ROVs can work in ...
Manila, with a population that has doubled since 1985, has no fallback as monsoon fails to materialize On July 11, the reservoir of the hydroelectric Angat Dam, which supplies Manila and other nearby areas with water, reached the critically low level of 160 m. Its normal minimum operating level is 180 m, and its normal high water level is 210 m. In the early part of March, water taps began to ...
CHC provided a complete water-to-wire equipment package to the City of Black River Falls, Wisconsin, for the upgrade of its Black River Falls Hydroelectric Dam, located on the east bank of the Black River in Jackson County, Wisconsin. This historic dam rebuilding project was completed in June 2012, and involved the installation of an additional low-flow generating unit. The water-to-wire ...
Expanding technology is the fastest way to slash greenhouse gas emissions and decarbonize the economy. Drs. Goldstein and Qvist are the authors of “A Bright Future: How Some Countries Have Solved Climate Change and the Rest Can Follow.” Dr. Pinker is a psychology professor at Harvard. As young people rightly demand real solutions to climate change, the question is not what ...
Intelligent Geo Data Logger Reads Vibrating Wire Sensors for Dam Monitoring A hydroelectric dam under construction in Serbia required dam monitoring of several environmental and structural properties to guarantee long-term strength and stability. Therefore the dam’s construction engineers put forth a proposal for a large number of geotechnical sensors to be installed and used during ...
Due to upstream interventions including barrage, dam and hydropower construction, the lower riparian region of Bangladesh faces acute water stresses, which hamper the agricultural, fisheries and livelihood activities of the river-dependent communities and impede the economic prosperity of the greater north-west region. ...
There are about 2,200 dams in the U.S. producing hydropower, and about 85,000 that don’t. ...

Of course, environmental concerns can play into the conversation as well. Hydropower, for example, can be ecologically damaging when disrupting river flow or fish breeding patterns, and in the United States, it can be controversial when dams infringe upon Native American land and water rights. Hydropower can be developed in such a way that ...
Water resources managers commonly rely on information collected by hydrometric networks without clear knowledge of their efficiency. Optimal water monitoring networks are still scarce especially in the Canadian context. Herein, a dual entropy multi-objective optimization (DEMO) method uses information theory to identify locations where the addition of a hydrometric station would optimally ...
