Italy is the 4th largest producer of electricity from hydropower in Europe, and it plays a large role in the power generation mix in the country, alongside the country’s Alpine neighbors – Austria and Switzerland. Their mountainous regions make the perfect spot for hydropower plants to be situated. Italy’s ambition is to generate 42,000 GWh of hydropower from 17.8 GW of installed capacity by 2020 (Source: International Hydropower Association).
This forms the perfect backdrop to the special Hydropower Day featuring in this year’s POWER-GEN Europe & Renewable Energy World Europe, which will take place in Milan, Italy, on June 21-23.
The conference is taking place under the patronage of the Italian Ministry of Economic Development, with the dedicated focus on hydropower being proudly supported by HydroWorld.com. Building on the legacy of PennWell’s landmark event HydroVision International, held in the USA annually, hydropower will be a running theme at the POWER-GEN Europe & Renewable Energy World Europe multi-track conference. Particular emphasis will be placed on storage, including pumped storage hydroelectricity.

Hydropower is Nepal's key to development and the country has an economically-viable potential of 40,000 MW of generation capacity of which it can export the surplus to neighbouring South Asian countries including India, an US government funding agency has said.
Developing sustainable hydropower generation will enable Nepal to balance its supply deficit in the dry season with the revenues made through exports during the season when river flows are high, US Agency for International Development said.
USAID said Nepal heavily depends on water resources to meet its energy demands as more than 90 per cent of its total electricity generation capacity is hydropower based.
"Hydropower plays a particularly important role in Nepal's economic future because of the scale of its potential," the agency said, estimating that Nepal has an economically-viable potential for more than 40,000 megawatts (MW) of hydropower generation capacity.

Australian Prime Minister Tony Abbott has promised that his government’s new 2030 climate target will be good for the environment, good for jobs and good for protecting the nation’s coal industry.

The Australian Prime Minister, Tony Abbott, seems to be hell-bent on a mission to undo the country's past carbon emission-reduction efforts. Last Sunday, the federal government announced that not only will it ban the Clean Energy Finance Corporation (CEFC) from investing in existing wind technology, but small-scale solar power projects as well. Instead, the CEFC will focus its energies on "emerging technologies."

With their green credentials, hydroelectric dams have been built at an exceptional rate all over the world. But their true environmental and ecological costs are slowly starting to unravel, as a new study shows how this renewable energy source can drive species out and dramatically reduce biodiversity.
“Hydroelectric dams have been thought to be an environmentally friendly source of renewable power – and in recent years they have been built to supply the burgeoning energy demands of emergent tropical countries,” explained Dr. Maíra Benchimol, who led the study published in PLoS One. “Our research adds evidence that forest biodiversity also pays a heavy price when large dams are built.”

As more wind and solar energy comes online, the people who run the power grid have a problem: how do they compensate for the variable nature of the sun and wind?
California plans to spend billions of dollars for batteries to even out the flow of power from solar and wind, much the way shock absorbers smooth out bumps on the road. But do they need to? Not at all!
In my research, I’ve found that we can accommodate a grid powered 50% by renewable energy without the use of batteries.

Engineers from Brigham Young University (BYU) are developing extremely waterproof surfaces that they believe could dramatically improve the efficiency of both power plants and solar energy systems. These surfaces, called superhydrophobic surfaces, are extremely difficult to wet since they cause water to aggregate and form beads that sit on the surface.

Tesla Motors already makes batteries for its electric cars. On Thursday, it’s expected to introduce battery systems for homes, businesses and electric utilities.
The spread of cost-effective batteries will fundamentally change the way the electric grid operates. Combined with other innovations, batteries in homes and businesses will transform how people and businesses treat electricity.
Along the way, these batteries will improve the efficiency and reliability of the grid overall.

Mongolia is hoping a massive dam on its largest river could provide much needed power and water for the country’s booming mining industry. However environmental groups are concerned that the hydroelectric power plant and a related pipeline project will do immeasurable environmental damage to oldest and deepest freshwater body in the world: Lake Baikal.
As Baikal sits just over the border in Russia, Mongolia risks seriously annoying its northern neighbour at at time when the lake is already experiencing problems with invasive algaealong its coasts, unregulated mining and a water level which just passed a “critically low” point.
