Intelligent Street Lighting Saves Up to 80% On Energy
Fact of the day: Most installations of solar panels take between 2 to 3 days. The work is not very noisy and our team of fully qualified installers of solar panels know what they’re doing.
Intelligent Street Lighting Saves Up to 80% On Energy
Delft University of Technology (TU Delft) is currently testing an intelligent street lighting system on its campus, which uses up to 80% less electricity than the current systems and is also cheaper to maintain. The system consists of street lights with LED lighting, motion sensors and wireless communication. This enables the installation to dim the lights when there are no cars, cyclists or pedestrians in the vicinity. Wireless communication between the street lights and a control room is also possible. The system was developed by TU Delft alumnus Management of Technology, Chintan Shah, who won a competition in 2010 with this concept for improving energy efficiency on the university campus.
80% savings on electricity
The Netherlands spends more than 300 million euros a year on electricity for street lighting. The network of street lighting also emits over 1.6 million tons of CO2 a year. The lights are always on at full power, regardless of whether there is anyone in the area. Compared with the current street-lighting system, Chintan Shah's intelligent system can reduce energy consumption and CO2 emission by up to 80%, is cheaper to maintain and can also help solve the problem of light pollution.
A safe circle of light
Shah's system consists of electronic gear that can be added to any -- dimmable -- street light. The system comprises street lights with LED lighting, motion sensors and wireless communication. At first glance, it looks a lot like a widely available type of garden light with a motion sensor, but there are significant differences. In Shah's system, all surrounding street lights light up if anyone approaches. And the lights never go out completely; they are dimmed to approx. 20% of the standard power. Passers-by move in a safe circle of light as it were. An added bonus is the fact that the lights automatically communicate any failures to the control room. This makes maintenance cheaper and more efficient than it is now.
Market introduction
The aim of the pilot on the TU Delft campus is to thoroughly test and fine-tune the system, to prevent swaying branches or passing cats from switching the lights to full power, for instance. Shah is working with his TU Delft spin-off company Tvilight on the market introduction of the system, which he expects to be profitable within 3-5 years. Shah: "This technology differs in certain aspects from the existing systems of other companies and all of this new technology has been patented." TU Delft is also curious to know the results of the pilot. Professor of Wind Energy, Gijs van Kuik, is actively involved in making the campus more sustainable: "We are delighted with this development. This is a promising opportunity to save energy on street lighting."
Competition
The realisation of this campus pilot was the prize Chintan Shah won in March 2010 in the Campus Energy Challenge, a competition for TU Delft students with ideas on improving energy efficiency on the university campus. The competition was initiated by the Delft Energy Initiative. This is the gateway to all energy research and education at TU Delft. It also promotes new projects in the field of energy.

Climate change aid - How to avoid corruption?
The poor, developing countries will no doubt need rich countries to provide them with huge financial aid in order to successfully tackle climate change. But with the huge funds, there is also a huge possibility for major corruption, especially if you consider that according to the Transparency International (TI) the 20 nations most vulnerable to climate change – where millions in grants and aid will be targeted - belong to the most corrupted countries in the world.
Corruption doesn't care about the health of our planet. There are many greedy people across the globe who care more about the money than our planet's future and without the introduction of adequate mechanisms to control climate change funds millions could end up in some dirty politician's pocket instead of being actually used to combat climate change.
The total investment into combating global climate change will reach almost $700bn by 2020, a huge sum that will likely open the door for corruption in many corners of the world. The main problem with climate change funds is that their mechanisms haven't yet been fully tested which almost invites embezzlement and misappropriation.
The carbon markets (the main financial tools to tackle climate change) have been some sort of a bad omen after the European Union's carbon market was forced to shut down after being constantly attacked by cyber-hackers. The result of these attacks is three million carbon credits stolen from government and private company accounts.
Things with climate change issue are anything but easy. Not only does the world have to ensure enough money for poor countries to tackle climate change, it also have to come up with the adequate controlling mechanisms in order to avoid corruption on large scale.
But make no mistake here as all countries are vulnerable to corruption though developing countries are the most vulnerable since they often lack even the basic anti-corruption mechanisms. It certainly looks like the battle against climate change will not only have to be focused on climate change but on various other factors too, including the possible corruption.
