Off-Grid Energy Options & Subsidies

In summary, most of the new technologies mentioned in the news are still years away from being practical for most people. Unless you are in a rural area or have very low energy bills, it is probably cheaper to just buy power from the grid. Solar PV is likely to be the most cost effective option in the near future, but it is still not practical for most people.

By now we have heard of all of these fascinating new technologies "just around the corner" that will "remove our energy dependence on corporate and foreign resources." In nearly every cable news interview, researchers claim that this new technology is "only five to ten years away." As a nation, we've been fed this five to ten year wait interval for more than 50 years and it is increasingly apparent that politicians, corporations, and governments give us a time to wait as a pacifier when they know very well that most likely, nothing's going to happen. Well, I'm sick of sitting around waiting for miraculous breakthroughs. My house is paid off and I don't have kids to worry about. Tell me what's available right now (I don't care how new the technology is) to power my house independently. What are the options available to me and what subsidies are available (if any). Thanks. I look forward to discussing this will all of you soon. :)

Depending on your latitude, solar panels would probably be the best bet at the moment. The main problem isn't really the power generation, the solar panel and inverter technology has definitely improved a lot over the years, the problem is energy storage if you really want to go entirely off grid. To have a fully independent system with sufficient energy storage for true off grid operation is very unlikely to be as cost effective as just using the grid. Plus you will have to spend time and money maintaining your installation.

Yes it's true that the media love to beat up these stories, but there have genuinely been large improvements in many of these technologies over recent years (solar panels in particular are like to become much more cost effective in the next few years due to recent advances in thin film designs). But still a reliable large scale energy grid has lots of advantages and I guess that why it’s still they still predominate. Personally I'm quite happy paying 12 cents a kW-hour to the supply company and not needing to have any generator, inverter and storage equipment to buy or maintain.

If you reduce your usage enough you can live off-grid with solar/wind or a combination in most rural areas.
Reduced usage can mean anything from no merely giant automatic washing machine down to electricity only for lights depending how much power you can produce / the site / how much land you have.

If you are in a city it's probably cheaper to buy power from the grid, perhaps with some direct solar water heating if you are in the south west. But if you are in a rural area where the alternative is a diesel generator then the technology is already there to do it better/cheaper.

I live in a residential suburban area outside of Buffalo, New York where energy costs skyrocket. The electric and gas companies love to play with our bills.

You can probably do solar water heating even in Buffalo, although since it freezes you want a vacuum tube system, not just a bunch of glass panels on your roof.

Wind is probably out in a residential neighbourhood - to work well the turbines need to be high and clear. The noise and tower height would probably mean zoning problems.
Solar is unlikely to pay back unless you go into real eco-mode, 12V lighting, no big appliances etc. But if the panels get cheaper and you power company has a buy back scheme it might be worthwhile soon.

Your best ROI on power bills in that climate is probably double glazing and a lot of wall/roof insulation.
 

1. What are the different types of off-grid energy options available?

Off-grid energy options include solar power, wind power, hydro power, biomass power, and geothermal power.

2. How do these off-grid energy options work?

Solar power uses solar panels to convert sunlight into electricity, wind power uses wind turbines to generate electricity, hydro power uses water flow to turn turbines and generate electricity, biomass power uses organic matter such as wood or waste to produce energy, and geothermal power harnesses heat from the earth's core to generate electricity.

3. Are there any subsidies or incentives for using off-grid energy?

Yes, there are various subsidies and incentives available for off-grid energy systems, such as tax credits, grants, and rebates. These incentives vary by location and type of energy system.

4. What are the benefits of using off-grid energy options?

Off-grid energy options can provide energy independence, reduce reliance on fossil fuels, and lower energy costs in the long run. They also have a lower environmental impact compared to traditional energy sources.

5. What are the challenges associated with off-grid energy options?

Some of the challenges include high upfront costs, maintenance and repair expenses, and the need for proper planning and management to ensure reliable and efficient energy supply. Additionally, off-grid energy options may not be feasible or practical in all locations.
