The 5 top cleantech solutions for your home

Clean Technica

What are the biggest and best cleantech solutions for a new home… or for any home, for that matter? Below is my list of the top 5-ish.

My wife and I are looking around for a new home. With such a big change, we plan to finally do many things that we’ve been pushing off “until we move.” I’m super eager to make a number of changes when we do find a place and move, including some cleantech ones. In this spirit, I thought I’d write an article on some top cleantech solutions I’d incorporate into a new home if possible, solutions which you could of course incorporate into any home — old or new.

1. Go Solar

This should be no surprise for our readers. Going solar is one of the best ways to do your bit to stop global warming (as well as air pollution, water pollution, unsustainable water use, and more). It’s also an excellent financial decision for a high number of people. The ROI on a solar power system beats the S&P 500 in 13 states and beats 5-year CDs in 43 states. Middle-class families who go solar via solar leasing save about $600 a year on their electric bill. On average, US homeowners who went solar in 2011 were projected to save over $20,000 over the life of their system, with the cost of solar power coming down tremendously since then. Going solar seems like common sense if you have a roof on which it would work and live in a state with decent solar incentives.

2. Switch To LEDs

LED lighting is finally cheap enough where it really, really makes sense to switch to LEDs instead of CFLs (and, of course, instead of incandescent light bulbs). A couple of different companies now offer LEDs for under $10 (even under $5 with rebates), LEDs which you can buy at Walmart and Home Depot.

3. Educate Your Thermostat

And, of course, get a thermostat that can learn from you. The most well known such thermostat is the Nest Learning Thermostat, which on my recent trip back to the US I noticed was for sale in Apple stores. Not that surprising, given that the founder of Nest, Tony Fadell, came up with the concept and initial design of the iPod. He apparently did great work at Apple for years before deciding to jump into the energy efficiency and smart home arena.

 

4. Get A Home EV Charger…

… for your new electric car. (Well, I’m just going to assume that have an electric car or will get one soon.) While plugging in to your normal electric socket is actually fine, there are still good rebates and even giveaways for faster home chargers for electric cars. I’d advise looking into it. I actually don’t plan to get a car anytime soon, not even an EV, so I’ll be passing on this one, but I thought it was a good addition to the list.

5. Get ENERGY STAR Appliances & Electronics… The Best Ones

The other big electricity users in your home are your appliances. If you are moving into a new home, try to get the most efficient appliances on the market… or, at least, quite efficient appliances with the ENERGY STAR rating. If you’ve got some super old appliances or electronics, many of you can also benefit if you upgrade. Look into it and crunch the numbers.

These super efficient appliances and electronics often have the best return on investment of anything you could buy. Plus, the savings are tax free! However, I would note that a ton of the products on the market these days are ENERGY STAR certified. So, really, look beyond the label and try to make sure you are really going for one of the most efficient options on the market.

So, whether you are looking for a new home or set on staying where you are, I think the above are some of the best cleantech solutions you could purchase. Let me know if you have more you’d put on the list, or if you have any gripe with the ones above.

    I agree with these as far as they go but my starting point is the house itself. In particular:

    1 Orientation and glazing: Ensure the windows to the north (south in the
    northern hemisphere) let in the sun from autumn to spring and are shaded
    to keep out the sun for the rest of the year. Minimise glazing from the
    other directions and particularly the west. Ideally locate utility
    areas such as carports, water tanks etc on the west of the house to
    shield it from the heat of the setting sun.

    2 Insulationand thermal mass: Ensure the ceilings and walls are insulated, and
    particularly in a cold climate have double or triple glazing though this
    is a good idea for any climate. Use the thermal mass of the building
    structure such as concrete floors and internal brick walls dampen the
    fluctuations of internal temperature. If you have concrete floors
    consider ceramic tiles instead of carpets so that they can act as an
    effective heat bank.

    3 Ventilation: Ensure the windows can be opened for cross flow ventilation when appropriate and that the house and its openings is sealed against drafts to minimise heat loss or gain when necessary

    4 Install solar hot water as well as solar power if possible. In our house we have an evacuated tube solar hot water system that provides us more or lees 100% solar heated water for 10 months a year.

    After that install your solar panels on the appropriately oriented roof and install your energy efficient lighting and appliances.

      Absolutely, and the configuration of glazing will generally also work well with nice, wide eaves, even in mid-latitudes.

    Interesting to note that the author didn’t really discuss the things you can do – insulation, draughtproofing, standby loads – to reduce your energy use prior to buying ‘stuff’. Part of the problem is that we think we need to buy stuff to live our lives. Simple low and no costs things we do every day can make a remarkable difference to the amount of energy we use. The greenest watt ever produced is the one you never use.
    * Turn the light off when you leave a room – LEDs especially come up to full brightness immediately.
    * Reduce the time of showers, install a ‘low flow’ showerhead – it takes a lot of energy to heat water.
    * Use a washing line rather than a drier
    * Turn appliances and chargers off at the wall when not in use
    * Lower the thermostat in winter and raise it in summer – every 1C difference equates to about a 10% difference in energy costs

    * When buying appliances, always get the smallest appliance that will do the job for you – apart from the lower up-front cost, they generally cost less to run. A half-empty fridge uses more energy than a full one.
    * Check the ‘kWh’ figure on the star label – the lower the figure, the better. A BIG TV will use more energy than a small one (and won’t require the addition of a home theatre room!)
    …and the best thing – doing this saves you money while conserving energy and helping to reduce greenhouse gases…

    I was thinking along the same lines as other commenters below/above. There are many things you can do before you start buying things. Hanging washing rather than drying, efficient cooking, wearing suitable clothing to match the temperature rather than going straight for the air con.

    Also, for heating, there are many inneficient methods out there that suck up huge amounts of energy.

    Finally, you can do all this and save more money by shopping around for the best electricity deal, particularly if it enables you to afford green electricity.

      Onnit Jonathan!

      I would say that without a sympathetic consumer, it’s impossible to make significant strides towards efficiency.

    In many applications, LEDs are definitely a good choice compared to CFLs — although they are still significantly more expensive. The big difference is the fact that LEDs don’t take 30 seconds to reach full brightness, are super long-lasting and have a superior light quality. And as far as energy efficiency, I agree — it’s a no brainer.

    Now I better start saving for that electric car!

    In relation to what others are saying about buildings, take a look at the BZE Buildings Plan, which details many effective measures individuals and businesses can take to reduce energy usage in the home and workplace.

    BZE researchers found that, in Australia, around 53% savings in energy usage was achievable retrofitting the average home. These savings fully offset the cost of impementing the changes to the home. Full document can be downloaded from this site: http://bze.org.au/download-zero-carbon-australia-building-plan

    Great comments from all about reducing energy use. Something that had stayed with me for a while though is the finding from ACF’s consumption atlas study that emissions from the food we eat and products we buy are four times as high as the energy we use directly in our homes. Great summary and graphics here: http://www.acfonline.org.au/sites/default/files/resource/res_Atlas_Main_Findings.pdf

    Given that, I think there needs to be much more focus on reducing consumption, buying and eating locally and reuse/recycling. Not the main focus of RenewEconomy or this article I know, but worth reflecting on…
