How To Build An Autonomous House – Episode 2

The video attached below is the second episode of my series about building an autonomous house on my land lot.

Today I finished translating subtitles for this episode, so you can watch it with english subtitles.

This episode shows the early spring on my lot. It was recorded in high definition, but I guess that to watch it in HD you would have to visit the blip.tv page for the episode.

I read once an interesting opinion, that investing your money in renewable energy sources pays off mostly when you’re retired.

Why is that?

All the alternative, renewable energy sources, provide you with free energy. If the system is designed properly (for example, photovoltaic panels coupled with wind turbine), you always have enough energy to fulfill your needs. And you don’t pay for it, except for the battery change every few years.

If so, the money you spend on those devices will save you money all the time you use them. You produce your own energy and thus you don’t need to buy it from the grid. And since energy costs are not expected to drop in the forseeable future, when you’re retired, they would account for a substantial part of your retirement pension.

I don’t believe that our european pensions would be more than 30-40% of our last paycheks, so we need to save our own money for the retirement. And in my opinion one of the best ways to save is to buy something that will generate you a real income or allow you to save money on something. Alternative energy sources are a great example.

  • Water as alternative energy source

    Water current can be effectively used to generate clean electricity. Generation of electricity from water currents can be accomplished in very large scales, by constructing dams or constructing tidal power plants and ocean surface wave power plants. It can also be done by individual homeowners (homesteaders) and small business owners, to generate and use small amounts of off-grid electricity. When setting up large scale hydroelectric power plants (or dams), the environmental impact of setting up the dam should also be considered as they can actually change the course of a river or create flood situations. The Grand Coulee Dam in the Washington state is an example of large-scale power generation units.

    Hydroelectric systems can also be used to generate power from rivers and oceans without constructing dams and examples of such power supplies include the tidal power generator units and ocean wave power generator units. The smalles example would be a new design of a floating waterwheel. (more…)
