Renewable energy is the only way forward

The battle humanity is waging against the corona virus is only the preliminary round, and after that, we have a much bigger and stronger opponent waiting for us, called the climate emergency.

The Economist’s regular cartoonist, KAL, summed it up neatly in his cartoon last week: the battle humanity is waging against the corona virus is only the preliminary round, and after that, we have a much bigger and stronger opponent waiting for us, called the climate emergency. That some people still may think that something as objectively and scientifically proven is still up for debate could be seen as one of the greatest achievements of the fossil fuel industry. It’s not. It’s the greatest threat to human life.

Pollution affects us all, very much so. In addition to being responsible for some seven million deaths annually, it makes us more vulnerable to all kinds of respiratory diseases, including, of course, those caused by viruses such as SARS-CoV-2, which could also become seasonal and repetitive. Not only do we know that we need to fix this problem: we also know that not doing so is killing us, and we now have a pressing example of this.

Electricity generated by fossil fuels accounts for 25% of harmful emissions in the world, while manufacturing and transport, also big consumers, are responsible for 21% and 14% respectively. If one change could have a major impact on the climate emergency, it would be the pivot to renewable energy. And the news in this regard could not be more propitious: the two fundamental components needed to do so, solar panels and batteries to store energy, are subject to economies of scale that make them increasingly efficient and affordable.

The economics of renewable energy are well known. Years ago, it was only competitive when backed by government subsidies. Now, the situation has been reversed: while oil companies receive more than $5 billion dollars each year in government subsidies, they bribe politicians who oppose environmental legislation, and they have no problem finding banks to lend them money, renewable energies are already cheaper than oil, gas or coal, a fact that should consequently change the global energy landscape. Microsoft’s ambitious plan to offset all emissions produced by the company’s activities throughout its history is driven by a desire to implement that kind of change.

Renewables accounted for 72% of new energy sources installed in 2019, backed by investments that could achieve returns of 800%. Coal, on the other hand, is a money-losing machine, and its economics are as toxic as its emissions. Reconstructing the energy supply map of a country, even those in the developing world, has never made more sense. Even a major coal producer like Australia plans to make huge savings from falling costs of renewables, and estimates that 90% of its energy supply could be based on solar and wind energy by 2040 without charging consumers to pay for installation. Norway aims to electrify all its domestic flights by 2040. Some oil companies are now investing in solar energy, partly as greenwashing, but partly just because it is profitable.

The United Kingdom has just gone for a record 23 days without using coal to power electricity generation, while American states like Iowa, Virginia and others are rethinking their plans, based on using renewable energy. The Democrats want to include action against climate change in the response packages to the coronavirus crisis, and are considering funding 30 million solar roofs across the nation.

Changing the world’s energy map seems like a costly thing to do, but in practice, it is cheap, especially if we factor in the disasters caused by fires, hurricanes, floods and so on. If we include the cost of treating the diseases it causes, or if we simply put a price on the viability of the human species as a whole, it’s clear that pivoting to renewables is a no-brainer.

A post-pandemic economic reconstruction based on restructuring the energy map makes sense. We know we have to do it, and we know the reason we haven’t done it so far is because it challenges the interests of a powerful few. The time has come to abandon outdated concepts, to change our mindset, and to put the use of renewables at the top of our list of priorities.

Like the wind

Ventum is the Latin word for wind, and there’s a lot of it on the southwestern coast of Norway, where the VDG headquarters are located. Company founder Christopher grew up on an island that was partly powered by windmills and took an early interest in wind power. Today, the Ventum project is all-consuming.

– It is my hobby, my work, my passion, he admits. – I dream of seeing thousands of rooftops with our windmill on it. I shall point at them an tell my kids look, your dad took part in this!

Christopher Bisset-Nilsen

Founder/Partner

The idea came up in 2016, when Christopher was working at a project in an especially windy industrial area south of Stavanger. «We should put windmills on the rooftops», a colleague joked a day when the windows were squeaking. And the seed was sown.

– It was time for me to do something new, something more fulfilling. It had to happen, and I knew the moment was now, Christopher recalls.

Using his experience from a versatile working career, Christopher started thinking, researching, sketching out possible solutions. After six months of hard work, a prototype of the vertical windmill was ready. Being a Star Wars enthusiast and finding similarities in shape, Christopher named it Death Star. – It worked ok but had its limitations.

Shortly after, Wolfgang entered the scene.

– We had known each other for some time. I had told him about the windmill project, and now he asked me if we should take it further together. Show me the money, I smiled, and, well, he did. Wolfgang is the kind of person you instantly trust. He comes on as so credible, he reads and understands people, builds relations, Christopher says.

Wolfgang Krohn

CEO/Partner

With the financial power to take the project a step further, things quickly escalated. The timing was ideal, with everyone talking about climate change and the need for new, green solutions.

– We were looking at an uncut diamond, an idea with a formidable potential, Wolfgang explains. – Just look at us now: We haven’t spent a dime on marketing, still the attention is already worldwide, and growing. It is kind of overwhelming, actually.

Still, not surprising: – We can offer a sustainable concept with no audible or visual noise no need for expensive infrastructure and not a threat to birdlife. Being scalable, the solution has a vast potential regarding both housing and industry.

Wolfgang catches his breath before continuing: – We are talking about an invention that has the potential to improve living conditions for millions of people around the world. Both urban and remote areas can be electrified, run by renewable energy that leaves absolutely no environmental footprint. Add the mobility – it can also be used whenever and wherever crisis occur, natural disasters or whatever.

An improved version 2.0 of what is now named Ventum saw the light of day in 2019.
In October, a version 3.0 will be launched in at the World Expo in Dubai.

– In three years, we will have a quality product that sells well on all five continents, Christopher predicts.

Rebekka Stumpf

Project Manager

The world has changed due to the ongoing climate issues. Now it’s all about thinking outside the box, finding new paths.

– For us at VDG, the future holds a lot of possibilities, Wolfgang emphasizes. – We work closely with solar cell companies, for instance. There are billions of flat rooftops around the world, we can offer reduced power. We are also looking into how to create new growth in deserts and other dried-out areas.

Rebekka, an Energy, Environment, and Society Graduate Student at UiS and was recruited on board as project leader only recently. She is very clear on the tasks ahead.

– We are a young company with every possibility to do things right from the beginning. There is no room for ethical flops, you have to be the real thing. Take circularity – using the right materials isn’t enough, you also have to know where they come from, how they are made, she says.

– There are so many challenges. CO2 emission being among the bigger one, of course, but you need to have a holistic approach, understand the bigger picture. Economy, politics, ethics, environmental issues – it is all connected, Rebecca states.

– Another vital aspect is the global food situation, she continues. – We are struggling with providing a sustainable food system that can feed everyone and have to think and act in accordance with that. Our solution does not compete with land that is or could be used for agriculture. Nor does it threaten wildlife, which is also of great importance.

– I believe our product will do things with peoples’ mindset, making them more aware of how they spend their energy, Wolfgang says. – It should be fun, too – you’ll have an app that shows how much power is being generated from your rooftop!

Christopher gets the final comment. – When you say «iPad», everyone knows what you mean. That’s how we want it to be – you say «Ventum turbine» and people nod.
