Denmark Just Produced 140% Of Its Electricity Needs Via Wind Power

Picture1

According to the chief commercial officer of the Ecofys energy consultancy, Kees van der Leun, a surge in wind farm installations could allow Denmark to produce half of its electricity from renewable sources by 2020 – that’s only five years away.

Not everyone is likely to be happy about this news, however. As The Guardian shares, the British wind industry is likely to view the Danish achievement with envy. This is no doubt because David Cameron’s government announced a withdrawal of support for onshore wind farms from next year, and planning obstacles for onshore wind builds.

“If we want to see this happening on a European scale, it is essential that we upgrade the continent’s aging grid infrastructure, ensure that countries open up borders, increase interconnection and trade electricity on a single market,” said Joy of the European Wind Energy Association.

Around three-quarters of Denmark’s wind capacity presently comes from onshore wind farms, which have strong government backing. One thing is for sure, the country is definitely putting the rest of the world to shame with these figures.

The disgusting truth about cruise liners

Britain Titanic

Thinking about taking a nice cruise over the holiday period? If you decide on it you’ll be one of about 20 million people who hop on the giant floating hotels every year.
And while it’s surely an incredibly relaxing way of spending some cash and searing in a sunglass tan before heading back to the office, it turns out cruise liners are even worse for the environment than you thought.
Here are some sobering facts from the Friends of the Earth, who graded 16 cruise liners on four environmental factors.
Each year cruise ships dump 3,78 billion litres of sewage into the ocean.
That number is difficult to get your head around, so think of it this way… A single 3000-person cruise liner generates 568,000 litres of sewage per week, which is enough to fill 10 backyard swimming pools.
To reiterate, that’s one cruise ship every week. As you’d expect, lots of sea creatures (particularly manatees off the Florida coast) are dying very stinky and unpleasant deaths that’s to this vast and crappy gift.
And according to the US EPA, each day an average cruise ship is at sea it emits more sulfur dioxide than 13 million cars and more soot than 1 million cars.

Have a look at the full findings here

Netherlands Is The 1st Country To Open A Solar Road For Public Use

Pre-fabricated-concrete-slabs2-700x400

The world’s first solar bike lane is soon to be available for use in the Netherlands! The bike path that connects the Amsterdam suburbs of Krommenie and Wormerveer is a 70-meter stretch of solar-powered roadway set to open for the public on November 12th, 2014.

The new solar road, which costs €3m (AUD$ 4,3m), was created as the first step in a project that the local government hopes will see the path being extended to 100 meters by 2016.

More complimentary plans are also on the table as the country intends to power everything from traffic lights to electric cars using solar panels.

School children and commuters see the bike road as very useful and a cool part of their daily commute, with approximately 2,000 cyclists expected to use it on an average day.

The road, which is named by the Netherlands Organization for Applied Scientific Research (TNO) as SolaRoad, is set to open in the next week. It is made up of rows of crystalline silicon solar cells, which were embedded into the concrete of the path and covered with a translucent layer of tempered glass.

“The surface of the road has been treated with a special non-adhesive coating, and the road itself was built to sit at a slight tilt in an effort to keep dust and dirt from accumulating and obscuring the solar cells.”

Since the path cannot be adjusted to the position of the sun, the panels will generate approximately 30% less energy than those placed on roofs. However, the road is tilted slightly to aid water run-off and achieve a better angle to the sun and its creators expect to generate more energy as the path is extended to 100 meters in 2016.

Actually, SolaRoad is not the first project aimed at turning roads and pathways into energy-harvesting surfaces. Solar Roadways are another major project -you can find out more about them by clicking HERE. The following video was posted online less than year ago, getting over $2.2 million to start the production.

“If all the roads in the US were converted to solar roadways, the Solar Roadways website claims, the country would generate three times as much energy as it currently uses and cut greenhouse gases by 75 percent.”

But the difference between the two projects is that Solar Roadways are working to integrate programmable LEDs in order to achieve custom road signs, heating components to drive away ice and snow, and specific kind of corridors to store fiber optic and TV cables.

How Much Room Do We Need To Supply The Entire World With Solar Electricity?

solar

In 2009, the total global electricity consumption was 20,279,640 GWh. The sun creates more energy than that in one hour. The tricky part is collecting that energy and converting it into useful electricity with solar panels. How much area would need to be covered with solar panels in order to capture enough energy to meet global demand? Actually, it’s not as much as you’d think.

The image above has three red boxes showing what area would need to be covered for Germany, Europe and the entire world.

So what the hell are we waiting for? Let’s start getting more solar panels on some rooftops and start chipping away at those boxes!

Sweden Runs Out of Garbage

shutterstock_96256664

Imagine a world where pollution is a non-issue, cities are pristine, healthy environments to live in, and little to no entanglements from discarded trash injures wildlife or clogs the oceans. In Sweden, this is almost a reality, yet it’s causing a paradoxical predicament for the recycle-happy country that relies on waste to heat and provide electricity to hundreds of thousands of homes.

The Scandinavian nation of more than 9,5 million citizens has run out of garbage; while this is a positive – almost enviable – predicament for a country to be facing, Sweden now has to search for rubbish outside of its borders to generate its waste-to-energy incineration program. It’s namely Norway officials who are now shipping in 80000 tons of refuse annually to fuel the country with outside waste.

The population’s remarkable pertinacious recycling habits are inspiration for other garbage-bloated countries where the idea of empty landfills is scarce. In fact, only 4 percent of all waste in Sweden is land-filled, a big win for the future of sustainable living. By using its two million tons of waste as energy and scrapping for more outside of its borders, this country is shown in international comparisons to be the global leader in recovering energy in waste. Go Sweden.

Public Radio International has the whole story. This (albeit short-term) solution is even highly beneficial for the Scandinavian country; Norway pays Sweden to take its excess waste, Sweden burns it for heat and electricity, and the ashes remaining from the incineration process, filled with highly polluting dioxins, are returned back to Norway and land filled.

Catarina Ostland, senior advisor for the Swedish Environmental Protection Agency, suggests that Norway may not be the perfect partner for the trash import-export scheme, however. “I hope that instead we will get the waste from Italy or from Romania or Bulgaria, or the Baltic countries because they landfill a lot in these countries” she tells PRI. “They don’t have any incineration plants or recycling plants, so they need to find a solution for their waste”.

There’s definitely something to be said about being ‘green’. Regardless of its sourcing, hopefully Sweden’s impeccable job of reducing its carbon footprint may serve as an example to other areas of the world that have more than enough trash to utilize and put to sustainable use.
