Off-grid vs. Being Energy Neutral by Net Metering
We still run into people who have a hard time understanding net metering, even though everyone seems to understand…

Turbines are also divided by their principle of operation and can be: An Impulse turbine, which is driven by a high-velocity jet (or multiple jets) of water. A Reaction turbine. The rotor of a reaction turbine is fully immersed in water and is enclosed in a pressure casing. The runner blades are profiled so that pressure differences … Read more
There are two ways of expressing the variation in river flow over the year: the annual hydrograph and the Flow Duration Curve or FDC, as illustrated below. The annual hydrograph is the easiest to understand, since it simply shows the day-by-day variation in flow over a calendar year. However, the FDC is more useful when … Read more
The first hydroelectric scheme was installed in Wisconsin in 1882…
Understanding the ways of using hydro power… grid tied, net metering, feed-in-tariff, and off-grid.
Net Metering Grid Tied Net Metered systems involve connecting your system to the power grid but you use the power, and it offsets your electric bill. If you don’t produce as much electricity as you use then the grid just supplies the difference and you get billed for that difference, if you produce more than … Read more
What’s the difference between Power and Energy? – know what you’re talking about.
Terms like weir and penstock got you confused? We’ll help you understand these as well and how a diversion hydro site works.
Understanding the types of hydro power – impoundment, diversion, pumped storage… we’ll explain them.
Understanding the anatomy of an impoundment hydro site – terms like head, flow , tail race, impoundment, depleted reach, got you confused? We’ll help you get oriented to understand not only the terms, but how an impoundment hydro site works.
