Hydro-Electric Power

This is one of the most interesting articles that I've read in recent months in the field of "Green Energy".

There have been hydro-electric projects meant for the ocean neat land masses which are enormous. Those are being studied today and should be available quite broadly in the near future. Since I haven't been following the development of that technology it's even possible those are available today. But, they're huge and very expensive and require extensive study of the environment to determine their impact before placement. The article linked above is about much smaller turbines of 1.5 - 3 meters rather than 10 meter-wide ocean hydro.

The smaller turbines are made to be safe for fish to travel through and yet they can be installed in almost any river and serve thousands of homes, perhaps even tens of thousands.

While we read constantly about Elon Musk and Tesla, there are wind turbines and solar panels and possibly even safe nuclear energy production techniques. We rarely hear about geo-thermal or hydro-electric because they aren't so easily placed where we want them. Traditional hydro has been done with huge dams to create large reservoirs of water. These new small turbines can be placed in many more sites on much smaller rivers and serve well. If the Green Energy revolution is to succeed we will need all these. When we combine them with energy-saving conservation by better construction techniques, a lot can be achieved.
