How to be a little greener

1 Reply Christopher Roberts

We all leave a footprint on the world, just by being alive we contribute to environmental degradation. No matter what you do, you can’t eliminate your effect (offset it maybe) on the world, but you can minimise it.

In this article I am going to look at some very simple things you can do to reduce the impact you have on the planet, making you a greener individual.

Water Usage

The amount of water we use has a big impact on the environment, as well as other people. Last April I posted an article which asked you to question your usage of water. I have included a brief summary of the article

Of all the water on earth, just 0.007% is drinkable, and whilst our usage of water and the number of people on earth are both rapidly growing, water supplies aren’t. Drought is a real issue in many areas of the world and one in nine people don’t have access to safe drinking water.

Rainwater storage tank

Wall mounted water butts are becoming more popular – a great way to collect and store rainwater.

Excessive use (and arguably wastage) of water via things like regular use of hose pipes and using water hungry appliances (like washing machines) when they have spare capacity, can easily be reduced, and can significantly decrease our water usage.

In the comments, there was some great feedback. Jonny suggested using a water butt to collect rainwater to water your garden, saying “it is really shocking to think that many people use drinking water to keep the lawn green“. Shane told us how he plays 5 minute songs when having a shower, so he know when it’s time to get out, and Jean noted how he tries to fix leaks as soon as he finds them, as they are a massive waste of water – and money!

Buy Local

Another step you can take which will reduce your carbon footprint is choosing local. In 2009, I wrote an article on the technology behind food, discussing the journey food takes, and the impact it has on the planet, getting it to our table. Although the figures might have slightly changed, the concept behind the article is still the same: buying local produce significantly reduces your carbon footprint.

Local doesn’t even have to mean that close. Ideally, within 20 miles of the shop you buy is the best sort of ‘local’, however even food that has been grown within 200 miles is much better than food that has been flown across the globe.

Local food not only promotes energy conservation, but it also supports local farmers. Farm shops are a really good place you can get local food, why not check out BigBarn, a site designed to help you find where you can get locally produced food.

Farm shops are a great place to source local food.

Reuse, Repair and Recycle Technology

It is important to use technology to its full potential, and to keep using it until it is no longer viable. Once something stops working, or is no longer able to fulfil your needs, whenever possible, repair or upgrade it. If your PC is starting to run a little sluggish, try to speed it up again (maybe visit my speed up your computer article) add some more RAM, upgrade the graphics card, and consider increasing the storage capacity.

As Jonny wrote last year, electronic waste is a real problem, computer components can be hard to recycle, and are often toxic. Therefore it is important to try to reduce electronic waste, and when it does occur, ensure it is disposed or/recycled properly.

If you have reused and repaired a device as much as possible, the next step is recycling. Recycling electronic waste is a growing industry, computer recycling and schemes which enable you to recycle mobile phones, so your technology is either properly recycled, or repaired and reused, either resold locally, or distributed to developing countries are becoming ever more common. Many firms (like the one I link to above) are even paying you for your old technology – reduce your ecological footprint, and get paid, what more could you ask for!

Save Energy

There seems to be a growing resistance to nuclear power, fossil fuels are running out and this matched with the lack of investment in renewables, is leading us to a global energy crisis. Every individual can make a difference, by reducing their consumption.

Electrical energyTurning off devices instead of leaving them on standby, switching to energy bulbs, and insulate your home and relatively simple and cheap ways to save energy, which we have probably all heard many times. Steps which involve using smarter technologies, such as getting Remote Heating Control installed and choosing smarter energy using devices are also good ways to save power, and are now also becoming more common.

In Summary

Four of the best ways you can reduce your environment impact are to: be more frugal with water; try and buy local produce; maintain technology for as long as possible, and then recycle it; and reducing your energy usage.

Feel free to critique any of my points, and by all means, suggest your own ideas below.

Top 10 Emerging Technologies

3 Replies Jonny Hankins

A couple of weeks ago the World Economic Forum published a document on its blog called “The top 10 emerging technologies for 2013”. I thought it might be interesting to have a look at what they say. The article can be read here. The comments are my own interpretation however.

World Economic Forum

1. Online Electric Vehicles.

About 100 years ago a scientist called Tesla demonstrated that electricity could be provided wirelessly. Today there is an idea that electric cars could drive while being recharged from electromagnetic fields created from cables under the road. The cars would need much smaller batteries of course.

The problem with this technology seems to be that it is difficult to measure how much power is taken, so difficult to bill for, nothing more than that. Take a look at this article about other ways of cutting pollution from transport systems.

2. 3D printing and remote manufacturing.

Much has been written and the technology undoubtedly carries advantages, but did you read my post about 3D printers potentially being used to make gun parts?

3. Self Healing Materials.

A great idea but this and other uses of nanotechnology and its production practices need to be regulated, as does the disposal of such materials. We don’t know enough about the effects upon human health as the recent report cited in another post on this blog demonstrates.

4. Energy Efficient Water Purification.

Must be a good thing. Some of Christopher’s thoughts on the issue here.

5. Carbon Dioxide conversion and use.

Geo-engineering offers the possibility of drawing carbon dioxide from the air and storing it underground, but this technology is extremely controversial. This article entitled Engineering a Solution to Global Warming gives an idea of some of the ethical debate surrounding such processes.

6. Enhanced nutrition to drive health.

Genetic modification of plants to make them more nutritional. Much has been written about the GM issue, it is certainly not as simple as it may sound. Great commercial interests are involved, as are problems of cross fertilization and non-reproducibility. See this article on the Bassetti Foundation website about the Vatican and its interests in the problem.

7. Remote sensing.

The buzz-phrase Smart City is all over nowadays. Have a look at this article for some ideas of how using sensors might improve urban life.

8. Precise drug delivery through nanoscale engineering.

Medicine is the area in which nanotechnology research shows its greatest potential. The problems of regulation still exist as brought up in the article above, but the possible advantages for society make this type of research extremely valuable.

9. Organic electronics and photovoltaics.

This article mentions solar panels made using fruit and vegetable juice instead of silicon, and the printing of circuits using organic materials is already a reality. Silicon is more efficient at the moment, but expensive, polluting and will eventually run out, but if scale is not a problem these solutions work well.

10. Fourth generation nuclear reactors and waste recycling.

Making nuclear energy cleaner and better is the goal. The questions of safety and sustainability as well as real cost are not raised however, again not an argument that can be expanded upon too much as it is extremely polarized, but there are cleaner and safer ways to produce electricity as the article about electricity generation cited above shows.

Well it looks like we got most of it covered at Technology Bloggers anyway, cutting edge as we are.

What renewable energy will you be looking into?

8 Replies Stephen Kenwright

The recent government incentive to promote ecological mind sets in the home is good news for the environment. Householders will be offered loans to deck out their homes with energy-saving appliances and equipment, including extra insulation and new boilers.

So what exactly do you need for your home?

Loft Insulation

If you’ve no loft insulation in your house, you could be losing up to a quarter of your home’s heat through the roof.

Most newer buildings are built to a standard taking into account this loss, but if you have a home that’s a little older, chances are you’re wasting all that lovely warmth and putting yourself out of pocket.

The Green Deal will provide owners of uninsulated homes the chance to reduce the energy used in heating by proving loft insulation.

Wall Insulation

You could be looking at losing up to a third of your home’s heat through uninsulated walls. Cavity walls are much more energy efficient than the solid walls of older houses, and if your home was built before around 1940, it’s more likely to have the latter.

With good wall insulation, you’re looking at making a real saving in energy bills so it’s a good idea to find out if you’re equipped to keep all the heat in your home.

Boilers

According to energy efficiency ratings, a band A boiler is 20% more energy and cost effective and a band G one. It’s usually the older boilers branded with the G rating.

If your boiler is outdated, you could be losing a lot of money from it. Modern, band A boilers have an energy efficiency rating of 90% and allow you to keep much better tabs on your energy use. It’s worth investing in thermostatic radiator valves so rooms that aren’t being used aren’t heated too.

Katy Jones at Dulas had this to say of the feed-in tariff scheme:

“The feed in tariff incentive from the UK government is encouraging many people to consider installing renewable energy technologies; it will naturally mean that some renewables companies also look to offer energy efficiency measures as part of their product portfolios.”

One single wind turbineProducts which will include solar panels. Fitted onto the roof, solar panels are capable of generating renewable energy for the home. And if they are producing more energy than your household needs, you can sell that energy back to the National Grid.

“From our perspective,” Ms. Jones continues, “Solar PV is a viable, cost effective way to generate free electricity and is especially good for high energy users looking to reduce their energy costs or with Carbon Reduction Commitments to meet.”

Other renewable energy sources will include micro wind turbines, which will be accepted on the Green Deal. Though they are a little small to provide all of your energy, it’s the little things that make a big difference to an energy bill.

With the government backing you, it’s never been a better time to look into renewable energy.
