Our energy system can be based on renewable energy

26.11.2008
We can change the Danish energy system to depend mainly on renewable energy and cut CO2 emissions by 50%. The big challenge lies in the system itself. This was one of the messages at DTU’s workshop on future energy systems.

For two days 160 scientists, businesspeople and government officers have been working to answer the question: What is the fastest way to an energy system with much less CO2 emissions? The first step is to integrate an interconnected intelligent power grid in Europe.

Denmark can become independent of fossil fuels by implementing efficiency improvements in all sectors including power stations, houses, industry and transport. At the same time, the share of renewable energy must be increased with more wind energy and increased use of biomass. In the transport sector we can replace fossil fuels with biofuels and we can also use electric cars which can be integrated into the power grid. The obstacle is the development of better batteries. Such a radical transformation of the energy system takes time. Accordingly, decisions and action are needed now. The transformation requires:

An interconnected intelligent power grid, integrated on a European level and able to store a higher level of renewable energy.

More research funds for new energy technologies and systems. We can achieve much with known technologies in the short term, but there is a need for research into new energy technologies and systems to enter the market after 2050.

Definite framework conditions and directives from the authorities. The energy sector needs this before beginning on huge investments in connection with a significant transformation of the energy system. For instance: instruments to promote the development of intelligent energy systems and stricter requirements for energy-using equipment, housing energy consumption, transport, etc. Such a development provides the Danish energy sector with great expansion opportunities on the international energy market.

Carbon capture and storage in power plants and energy-consuming industries seem to be necessary until we are able to phase out fossil fuels.

At the global level, all known sustainable energy technologies must be used in order to control CO2 emissions. The solutions are quite different in various regions of the world. In countries with rapidly growing developing economies like India and China it is obvious to expand with the best technologies, but it takes extensive international cooperation. In the world's least developed countries there is a need for providing modern clean energy and electricity to everyone. Here the world's major economies should help transfer clean energy technologies, based on both fossil fuels and renewable energy.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

Key advance for future topological transistors

Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
