Water energy has been harnessed for thousands of years in the likes of water to drive water-wheels.
It is probably one of the most predictable and reliable of renewables.
Considered by some to be the cleanest renewable energy, but perhaps the most controversial.
Wind, like water, has been harnessed for many years for milling grain and pumping water.
The original solar panels, are probably the oldest and simplest of all renewable technologies.
They provide free hot water utilising the suns’ energy.
You don’t have to be that technically minded to build your own.
They can be made from waste products such as old radiators, panes of glass and empty aluminium drink cans.
An expensive, high embodied energy, way to utilise the sun’s energy. However, they are easily available and have been made more popular through government payback incentives.
Many panels may be needed to provide energy depending upon your household energy consumption.
On a positive note, photovoltaic panels can supply energy (to the grid) which can cover your household energy use and maybe even make you some cash from a payback incentive.
Can range from district heating and biomass boilers to the simple wood-burning stove.
A wood-burning stove with a back boiler can heat a well-insulated home and your water for very little financial outlay.
You can keep cost down even further if you can grow your own trees.
Biomass boilers are more expensive, well suitable for community use and require processed and packaged wood pellets or chips.
A way to tap into heat from the earth’s stored energy. You would need a large garden or area of land and considerable quantities of pipes to source and use free energy from the earth.

and guidance to support your informed energy choices, check out:
How will you heat and power your natural home?
The best source of energy is that which requires minimum technology or
moving parts, such as sunlight in a south facing room,
heat stored and released in thermal mass materials or wood burning in a stove.
A build requires energy in many forms.
Embodied energy in materials and production.
Energy used in transportation and construction.
Energy used in the building’s lifetime, including space and water heating.
