We can learn a lot about clean energy from Scandinavian nations

Published

Scandinavia has managed to reduce its carbon emissions and achieve considerable economic growth. As a result, countries like Denmark and Sweden have become some of the greenest in Europe.

The exploitation of finite resources is a double-edged sword. Not only is it harming the planet for future generations, but it will also ultimately affect economic return. However some countries in Europe seem to have embraced the concept of sustainable economics and clean energy more than others.

These nations have recognised that a reliability on limitless natural resources such as the wind and sun ensure a brighter future for their people and businesses.

Among the most virtuous places in Europe is Denmark. Despite the fact that in 2009, oil and natural gas represented 36% and 22% respectively of the country’s total primary energy supply, it has gradually moved towards reducing its CO2 emissions.

Denmark never forgot the 1973 global oil crisis and the drastic effects this had on the Danish way of life”, freelance journalist Richard Steed, who has worked for Denmark’s Ministry of Foreign Affairs, tells Blue & Green Tomorrow.

It realised that greater energy efficiency and a more diversified energy supply would help it with this goal. Since then, it has had an impressive record of pioneering onshore and offshore wind farms, district heating systems, and energy generated from waste.”

Steed says that Denmark’s economy grew by 45% from 1990 to 2007 and its CO2 emissions were reduced by more than 13%. This shows that ‘green’ and ‘growth’ are not conflicting terms, and that they indeed can coexist – something that UK chancellor George Osborne, who famously said, “We’re not going to save the planet by putting our country out of business”, could learn from.

Denmark is planning to produce 100% of its energy from renewables by 2050 and has a number of ambitious green energy goals in place.

The main goal for Denmark is to have its own local energy security, not having to rely on anyone else to keep the lights on”, says Steed.

But the Danes are not the only ones in Scandinavia aiming to reduce their dependency on oil: Sweden has also reduced its fossil fuels imports since 1973 and is planning to become oil-free in the not-too-distant future.

The Swedish government has launched a multi-billion dollar programme to promote renewable energy, whose productivity in the country has risen from 33.9% in 1990 to 43.3% in 2009.

In 2006, the Swedish minister of sustainable development Mona Sahlin told The Guardian, “We want to be both mentally and technically prepared for a world without oil.

The plan is a response to global climate change, rising petroleum prices and warnings by some experts that the world may soon be running out of oil.”

In 2008, Sweden and Finland had the highest rate of renewable energy consumption in Europe.

It is fundamental part of the Scandinavian psyche to protect and respect nature”, adds Steed.

Denmark is a biking nation at heart and Copenhagen recently announced ‘there are more bikes than people in the city’. Danes see bikes as a cheaper and healthier way to get around the city than sitting in their cars.

To buy a car in Denmark is extremely expensive because of the heavy taxes, so owning a car is seen as a luxury. Obviously more bikes means less pollution and cars just don’t have the same social status as in the UK or America.”

The UK – and indeed Europe – could learn a lot from Scandinavian renewable energy policies. Harnessing our plentiful renewable resources – both offshore on onshore – makes not only financial sense, but also environmental and social sense.

Increasing your home’s energy efficiency is one of the smartest moves you can make as a homeowner. It will lower your bills, increase the resale value of your property, and help minimize our planet’s fast-approaching climate crisis. While major home retrofits can seem daunting, there are plenty of quick and cost-effective ways to start reducing your carbon footprint today. Here are five easy projects to make your home more sustainable.

1. Weather stripping

If you’re looking to make your home more energy efficient, an energy audit is a highly recommended first step. This will reveal where your home is lacking in regards to sustainability suggests the best plan of attack.

Some form of weather stripping is nearly always advised because it is so easy and inexpensive yet can yield such transformative results. The audit will provide information about air leaks which you can couple with your own knowledge of your home’s ventilation needs to develop a strategic plan.

Make sure you choose the appropriate type of weather stripping for each location in your home. Areas that receive a lot of wear and tear, like popular doorways, are best served by slightly more expensive vinyl or metal options. Immobile cracks or infrequently opened windows can be treated with inexpensive foams or caulking. Depending on the age and quality of your home, the resulting energy savings can be as much as 20 percent.

2. Programmable thermostats

Programmable thermostats have tremendous potential to save money and minimize unnecessary energy usage. About 45 percent of a home’s energy is earmarked for heating and cooling needs with a large fraction of that wasted on unoccupied spaces. Programmable thermostats can automatically lower the heat overnight or shut off the air conditioning when you go to work.

Every degree Fahrenheit you lower the thermostat equates to 1 percent less energy use, which amounts to considerable savings over the course of a year. When used correctly, programmable thermostats reduce heating and cooling bills by 10 to 30 percent. Of course, the same result can be achieved by manually adjusting your thermostats to coincide with your activities, just make sure you remember to do it!

3. Low-flow water hardware

With the current focus on carbon emissions and climate change, we typically equate environmental stability to lower energy use, but fresh water shortage is an equal threat. Installing low-flow hardware for toilets and showers, particularly in drought prone areas, is an inexpensive and easy way to cut water consumption by 50 percent and save as much as $145 per year.

Older toilets use up to 6 gallons of water per flush, the equivalent of an astounding 20.1 gallons per person each day. This makes them the biggest consumer of indoor water. New low-flow toilets are standardized at 1.6 gallons per flush and can save more than 20,000 gallons a year in a 4-member household.

Similarly, low-flow shower heads can decrease water consumption by 40 percent or more while also lowering water heating bills and reducing CO2 emissions. Unlike early versions, new low-flow models are equipped with excellent pressure technology so your shower will be no less satisfying.

4. Energy efficient light bulbs

An average household dedicates about 5 percent of its energy use to lighting, but this value is dropping thanks to new lighting technology. Incandescent bulbs are quickly becoming a thing of the past. These inefficient light sources give off 90 percent of their energy as heat which is not only impractical from a lighting standpoint, but also raises energy bills even further during hot weather.

New LED and compact fluorescent options are far more efficient and longer lasting. Though the upfront costs are higher, the long term environmental and financial benefits are well worth it. Energy efficient light bulbs use as much as 80 percent less energy than traditional incandescent and last 3 to 25 times longer producing savings of about $6 per year per bulb.

5. Installing solar panels

Adding solar panels may not be the easiest, or least expensive, sustainability upgrade for your home, but it will certainly have the greatest impact on both your energy bills and your environmental footprint. Installing solar panels can run about $15,000 – $20,000 upfront, though a number of government incentives are bringing these numbers down. Alternatively, panels can also be leased for a much lower initial investment.

Once operational, a solar system saves about $600 per year over the course of its 25 to 30-year lifespan, and this figure will grow as energy prices rise. Solar installations require little to no maintenance and increase the value of your home.

From an environmental standpoint, the average five-kilowatt residential system can reduce household CO2 emissions by 15,000 pounds every year. Using your solar system to power an electric vehicle is the ultimate sustainable solution serving to reduce total CO2 emissions by as much as 70%!

These days, being environmentally responsible is the hallmark of a good global citizen and it need not require major sacrifices in regards to your lifestyle or your wallet. In fact, increasing your home’s sustainability is apt to make your residence more livable and save you money in the long run. The five projects listed here are just a few of the easy ways to reduce both your environmental footprint and your energy bills. So, give one or more of them a try; with a small budget and a little know-how, there is no reason you can’t start today.

Swimming pools are undoubtedly one of the most luxurious features that any home can have. But environmentally-conscious homeowners who are interested in having a pool installed may feel that the potential issues surrounding wasted water, chemical use and energy utilized in heating the water makes having a home swimming pool difficult to justify.

But there is good news, because modern technologies are helping to make pools far less environmentally harmful than ever before. If you are interested in having a pool built but you want to make sure that it is as eco-friendly as possible, you can follow the advice below. From natural pools to solar panel heating systems, there are many steps that you can take.

Choose a natural pool to go chemical free

For those homeowners interested in an eco-friendly pool, the first thing to consider is a natural pool. Natural swimming pools utilise reed bed technology or moss-filtration to naturally filter out dirt from the water. These can be combined with eco-pumps to allow you to have a pool that is completely free from chemicals.

Not only are traditional pool chemicals potentially harmful to the skin, they also mean that you can contaminate the area around the pool if chemical-filled water leaks or is splashed around. This can be bad for your garden and the environment general.

It will be necessary to work with an expert pool builder to ensure that you have the expertise to get your natural pool installed properly. But the results with definitely be worth the effort and planning that you have to put in.

Avoid concrete if possible

The vast majority of home pools are built using concrete but this is far from ideal in terms of an eco-friendly pool for a large number of reasons. Concrete pools are typically built and then lined to stop keep out any bacteria. This is theoretically fine, except that concrete is porous and the lining can be liable to erode or break which can allow bacteria to enter the pool.

It is much better to use a non-porous material such as fibreglass or carbon ceramic composite for your pool. Typically, these swimming pools are supplied in a one-piece shell rather than having to be built from scratch, ensuring a bacteria-free environment. These non-porous materials make it impossible for the water to become contaminated through bacteria seeping into the pool by osmosis.

The further problem that can arise from having a concrete pool is that once this bacteria begins to get into the pool it can be more difficult for a natural filtration system to be effective. This can lead to you having to resort to using chemicals to get the pool clean.

Add solar panels

It is surprising how many will go to extreme lengths to ensure that their pool is as eco-friendly as possible in terms of building and maintaining it but then fall down on something extremely obvious. No matter what steps you take with the rest of your pool, it won’t really be worth the hassle if you are going to be conventionally heating your pool up, using serious amounts of energy to do so.

Thankfully there are plenty of steps you can take to ensure that your pool is heated to a pleasant temperature while causing minimal damage to the environment. Firstly, gathering energy using solar panels has become a very popular way to reduce consumption of electricity as well as decreasing utility bills. Many businesses offer solar panels specifically for swimming pools.

Additionally, installing an energy efficient heat pump or boiler to work in conjunction with your solar panels can be hugely beneficial.

Cover it!

Finally, it is worth remembering that there are many benefits to investing in a pool cover. When you cover your pool you increase its heat retention which stops you from having to power a pump or boiler to keep it warm. This works in conjunction with the solar panels and eco-friendly heating system that you have already had installed.

Additionally, you cover helps to keep out dirt and other detritus that can enter the pool, bringing in bacteria. Anything that you can do to keep bacteria out will be helpful in terms of keeping it clean.
