The science behind solar electric panels

Solar electric panels or photovoltaic cells have been under development since the photovoltaic effect was first discovered by French physicist A.E. Becquerel in 1839.

Solar power systems becoming commonplace

Solar power systems, long thought to be the domain of the so-called ‘green movement’ have become commonplace in so many settings and applications as to be almost invisible to anyone not paying attention.

Split-phase converters open new doors for energy

Alternating current powers the modern world and is the energy source our home appliances and conveniences are designed to use.

Hydrogen as fuel has shortcomings

Hydrogen has been touted as the saviour of the world’s modern way of life. Even so, there are some major shortcomings to this source of energy.

Science and technology, and amazing discoveries

Science and technology, once the domain of an elite few, currently is available to everyone in the educated world.

Design for an energy-efficient home

In the planning of a rural off grid home, or any energy efficient home, controlling electrical consumption should be a major design consideration.

Harnessing the wind to work

For millennia, the wind has been harnessed for work.

Geothermal a viable alternative to nuclear or coal-fired options

Geothermal is defined as: relating to or produced by the heat in the interior of Earth.

Backup systems run homes, offices when electrical grid goes down

Ice storms, high winds and lightning all threaten the electrical grid and its continuous operation.

Hydrogen home technology starts to show up in houses

The hydrogen home technology has started to show up in a number of places in North America.

Living off the grid isn’t rustic

When you think of living off grid, most people have visions of living in a recreational vehicle with 12-volt lights, propane fridges and a generator running every night.

Off the grid? You still need a generator

You have installed a wind turbine and a solar array on a tracker for your new off-grid home.

How to go solar

What is the process for putting a grid-tied solar array in your home and is it worth it?

Fuel cell technology coming soon — just not here

A fuel cell is an electrochemical cell that converts a source of fuel into an electric current.

Alternate energy systems beginning to prove themselves

Imagine: it is a beautiful blue-sky day; the wind is blow steady at 18 km/h, the wind turbine spinning effortlessly, the solar panels are tracking the sun as it treks across the horizon.

Sun can do work for ranchers to get stock watered

Watering stock in rural areas present some challenges.

Your own hydroelectric source

When we think hydroelectric, we usually envisage a large reservoir, dammed by artificial means, driving large megawatt turbines, spinning endlessly in order to light our civilization.

Some applications for alternative energy

Over the past few months, we have looked at a number of different types of alternate energy equipment, from solar panels for producing electricity to towers that hold wind turbines in the sky.
