Why challenges lie ahead for the bond between hydropower in addition to also water

Hydropower is actually the biggest source of renewable electricity inside the earth in addition to also is actually responsible for producing roughly 17 percent of the planet’s electricity, according to the International Energy Agency.

The scale of some hydropower projects, such as the Itaipu facility situated between Brazil in addition to also Paraguay, is actually vast. Since operations began in 1984, the site has generated over 2.4 billion megawatt hours of energy.

“Our generating units are 700 megawatts each,” Juliano Portela, an engineer at Itaipu Binacional, told CNBC’s Sustainable Energy last year. “We have 20 generating units installed, which comprises a total of 14,000 megawatts.”

In terms of their longevity, hydropower facilities can be built to stand the test of time. As well as speaking to those working at Itaipu, “Sustainable Energy” also heard via Gilkes, a British business which specializes inside the development of hydropower projects.

Andy Eaton, its international hydro sales manager, said which some machines had been running for more than 100 years. Little tweaks are required today in addition to also then.

“Recently, we’ve carried out some upgrading work… of some equipment on a tea estate in Kenya, where they have several machines of ours dating back to the 1920s,” he said. “We haven’t definitely carried out too much mechanically on the turbines, the idea’s just an upgrade on the electrical side of the equipment where over a period of time the software, etcetera, has changed.”

the idea goes without saying which water is actually crucial to hydropower, as the idea is actually to a huge number of additional things which make the earth go round.

Looking at the bigger picture, the idea’s clear which there are challenges ahead.

“Future water scarcity is actually going to mean which we’re going to have to move water further distances, move water via afar to… where the idea’s needed,” Kala Vairavamoorthy, executive director of the International Water Association, told CNBC’s “Sustainable Energy”.

“which’s going to require more energy because water is actually heavy,” he said. “If you couple which with our interest in low carbon energy, many of those technologies are going to require quite a lot of water, so This kind of ‘water-energy nexus’ comes into play.” Broadly speaking, the water energy nexus can refer to the relationship in addition to also interdependency between water in addition to also energy.

“If you… wrap all of This kind of into the economic transformation which’s taking place in developing countries, most of which economic transformation is actually going to require lots of water in addition to also lots of energy,” Vairavamoorthy said, adding which he was hopeful which challenges could be navigated thanks to “great innovations” taking place in technology.
