⭐️ About this Episode:
Finally, its time to start working on creating Hydroelectric POWER for the Off Grid Cabin. The 1st step is building a Dam to capture the water so that we can force it to the water wheel that we will be creating in upcoming episodes. Will this work? I SURE HOPE SO!!! Everything we have worked for over the past months all hinges on this idea that our cabin will be truly off grid and powered by WATER!! At best its a theory that we can create enough power to run the cabin but only time will tell. So stay tuned to see how this project comes together!

We are a Full-time RV Living family with 4 kids who in 2018 Sold Everything to be a Family who is together all the time!! Homeschooling our kids and going on amazing adventures and seeing incredible places!! We just sold our 1st RV set up which was a truck and 5th wheel (see video of why we switched here: ) to get our new RV set up with a Class A and Jeep Wrangler! Now are building an OFF GRID CABIN on 50 acres in the Ozarks of Missouri as a home base between travels.

📖You can learn more about engineering in our technical encyclopedia:


This type of power plant converts potential energy to electrical energy, or, electrical energy to potential energy. They achieve this by allowing water to flow from a high elevation to a lower elevation, or, by pumping water from a low elevation to a higher elevation. When water flows to a lower elevation, the power plant generates electricity. When water is pumped to a higher elevation, the power plant creates a store of potential energy. Pumped storage plants use Francis turbines because they can act as both a hydraulic pump and hydraulic turbine.

Pumped storage power plants are used to balance the frequency, voltage and power demands within the electrical grid. Pump storage plants are often utilised to add additional megawatt capacity to the grid during period of high power demand, for this reason, pumped storage plants are referred to as ‘peaking’ plants.

Because pumped storage plants can provide electrical grid operators with power ‘on-demand’, they have a high level of dispatchability (the ability to provide power to the grid as needed).

Irrespective geographical location, all pumped storage plants require an upper and lower reservoir. The difference in elevation between the upper and lower reservoirs is referred to as the ‘head’ (head of pressure) and it must be significant in order for the plant to operate efficiently.

A penstock connects the upper reservoir to a Francis turbine located in the power house. A draft tube and tail race connects the Francis turbine to the lower reservoir.

Operation – Generating Power (Electricity)
Water flows from the upper reservoir, through the penstock, and to the Francis turbine. As the water passes over the Francis runner blades, a pressure differential is created that causes torque (rotary force) to be applied to the runner. The runner begins to rotate.
The turbine runner is connected on a common shaft to an electrical generator. As the runner rotates, so too does the generator rotor. As the rotor rotates through the electromagnetic field within the generator, it induces current in the stator windings and electrical current begins to flow. The electrical current is usually then dispatched to end consumers via a switchyard and electrical transformer.

Water discharged from the turbine runner enters into a draft tube where some of the kinetic energy is recovered and converted to potential energy; the water then enters the tail race and is discharged to the lower reservoir.

In this example, the potential energy of water was converted by the turbine runner into mechanical energy. The mechanical energy was transferred on a common shaft to a generator, which converted the mechanical energy to electrical energy. The entire process can be continuous until the upper reservoir is emptied.

Operation – Storing Potential Energy
Water is pumped from the lower reservoir to the upper reservoir by the Francis turbine runner. The flow path is the same as when generating electricity, except the flow direction is reversed.

Pumped Storage Economics
Pumped storage plants rely upon the varying price of electricity to make a profit. Many thermal power plants (coal fired, gas fired etc.) cannot increase or reduce their MW output quickly because this would place large thermal stresses on the power plant components (water tube boiler, piping etc.). For this reason, thermal power plants produce almost as much power at night, as they do during the day.

78. Net-Zero 101 – The secret of building super energy efficient net-zero homes

Energy Efficiency No Comments »

Net-zero homes first appeared in 2007, but they are taking North America by storm. In part 1 of our Chasing Net-zero series we talk to net-zero pioneer Peter Amerongen about the amazing history of these super energy efficient solar-powered homes and Mike Turner about the secrets of building a net-zero home.

Richard Trethewey checks out an Idea House in development and learns about energy efficiency building techniques.

SUBSCRIBE to This Old House:

Richard Trethewey goes to Devens, MA to visit a new house with advance building techniques. He meets builder Dan Gainsboro who says the entire heating season will only cost 00 or less for this new house—considerably lower than what our homeowners were paying to heat their house. He shows Richard how the houses in the development are built using 2×6 walls with insulated panel sheathing for a water and air-tight shield. Walls are insulated on the inside and the window openings are wrapped with flashing tape and even the headers are insulated. They used triple glazed windows throughout. The finished Idea House is a lovely small scale home with an open floor plan. The light fixtures use LEDs and the appliances are all Energy Star rated. In the well-insulated basement, there’s no mechanical room because mini-split heat pumps are used to heat and cool the entire house. And finally, Dan shows Richard the solar panels on the south facing roof of the garage. On a sunny day, the panels generate enough electricity to power the house for a family of four.

Energy efficiency and energy savings: a view from the building sector

Energy Efficiency No Comments »

The GBPN has just released a report entitled “Energy efficiency and energy savings: a view from the building sector” commissioned to the Economist Intelligence Unit. The survey explores how real estate and construction executives in the European Union, India, China and the USA approach energy efficiency regulation in their business.

The report highlights that businesses, motivated by the potential for cost cutting, are embracing energy efficiency.

Given the fact that buildings account for about a third of total energy use worldwide and of energy related CO2 emissions, the research suggests that business leaders are ready to go deep and are waiting for the right policy signals that can scale up energy efficiency in the sector.
