HYDRO: More Ocean Power Needed

The heat and drought affecting many global locations has cut into renewable energy produced by hydroelectric sources, increasing the demand for coal as a replacement.

While we often think of solar and wind as being the leading forms of renewable energy, it’s actually hydro that holds top spot:

OCEANS ARE A VAST RESOURCE, BUT…
Equipment that produces tidal energy has shown the ocean to be a harsh environment, but if climate change and supply/demand are the driving forces, much more development and implementation is on the horizon.

The website EnergyStartups lists nine tidal energy startups:
The website Power Technology lists the five biggest tidal power plants in 2014

CNN Business – These companies are using oceans and rivers to generate electricity
Off the coast of Scotland, Orbital Marine Power operates what it says is the “most powerful tidal turbine in the world.” Verdant Power is using similar technology to generate power near Roosevelt Island in New York City’s East River. Although not on the market yet, Verdant’s turbines set up as part of a pilot project help supply electricity to New York’s grid.

Hydroelectric turbines could soon power Parliament by harnessing the tidal power of the Thames
The Speaker’s proposals emerged after Liz Truss announced she was lifting the ban on fracking as part of the Government’s response to the energy crisis. Allies also pointed out that the late Queen had installed hydroelectric turbines at Windsor Castle and at her beloved Balmoral. 

Nova Innovation talks tidal energy with UK Chancellor
UK’s Chancellor of the Exchequer Nadhim Zahawi has paid a visit to Nova Innovation to learn more about tidal energy, the company’s technology and route to market for the industry.

SWEL Promises Cleanest, Cheapest Energy Ever — We’ll See
Sea Wave Energy Ltd. (they go by “SWEL,” natch) has spent the better part of the last decade developing a floating, wave-riding generator that the company claims will produce a whole lot of tidal energy for not a whole lot of money. The “Waveline Magnet” floats follow the contours of the water, creating a serpentine motion that works on lever arms to drive low-cost electrical generators inside the spine units.
