Back in a Bit

Bright ideas

From today, the manufacture or import of the 60W filament bulb is no longer permitted across Europe. Opinions obviously differ on whether this is a bold environmental step forward, or an example of nanny state philosophy.

The decision makes me mindful, once again, of the Digest of UK Energy Statistics, or DUKES Report. Published annually by the Department of Energy and Climate Change, it summarises all sources and uses of energy in the United Kingdom.

Broadly, the report illustrates that the UK’s total energy consumption could be divided into three approximately equal groups. The first is transport; the second is heating; the third is everything else. So, if you were to add up the energy used by every light bulb, every computer, every appliance and every machine across the country, the total would equal that used for heating alone.

So, if the decision on European light bulbs is environmentally driven, it can be considered only a small start. Indeed, the question of whether there is a significant environmental benefit to using “energy-saving” bulbs is still debated. Furthermore, the tax on energy for heating in the UK is set around 5%, whereas the tax on petrol and diesel is over 50%. If Europe is so concerned with environmental issues, we would do well to to divert our attention away from how we light our homes and workplaces, and instead onto how we heat them.

Earth’s systems in rapid decline

Protecting bits of nature here and there will not prevent humanity from losing our life support system. Even if areas dedicated to conserving plants, animals, and other species that provide Earth’s life support system increased tenfold, it would not be enough without dealing with the big issues of the 21st century: population, overconsumption and inefficient resource use. Without dealing with those big issues, humanity will need 27 planet Earths by 2050, a new study estimates.

The size and number of protected areas on land and sea has increased dramatically since the 1980s, now totalling over 100,000 in number and covering 17 million square kilometres of land and two million square kilometres of oceans, a new study reported Thursday.

Gemasolar Concentrated Solar Power achieves key milestone

The Gemasolar Concentrated Solar Power plant near Seville, Spain, has achieved a full 24 hours of solar power production one month after starting commercial operation. The 19.9 MW plant uses a huge array of mirrors to heat a molten salt storage system in the central tower which is then used to run steam turbines, resulting in the ability to continue energy production after the sun goes down.

Nokia develops phone that recharges itself without mains electricity

A new research prototype phone from the company is able to power itself on nothing more than ambient radiowaves – the weak TV, radio and mobile phone signals that permanently surround us. The power harvested is small but it is almost enough to power a mobile in standby mode indefinitely without ever needing to plug it into the mains, according to Markku Rouvala, one of the researchers who developed the device at the Nokia Research Centre in Cambridge, UK.

Clean Coal? 10 of the World’s Dirtiest Power Plants

Drax provides 7% of the electrical power required by Britain. Drax is actually the most carbon efficient coal-fired power plant in the UK, even though it generates around 1.5 million tons of ash and 22.8 million tons of carbon dioxide each year, which just goes to show, even the cleanest of coal-fired power plants are dirty.

Wrightspeed X1

It all started in 2005 when Ian Wright, Wrightspeed founder and CEO, built the X1–to date the fastest street legal electric car in the world.The X1 is a concept car and a test platform based on a modified Ariel Atom. It is not a production car, and never will be. The X1 proves that electric drive can deliver extreme performance without compromising its intrinsic efficiency.
