Air quality is terribly important. There are various ways in which air can be polluted and various ways to test that the air quality is of a sufficiently high standard so as not to present a hazard to human health. One of the most important ways of measuring air quality is to measure pollution particles in the air that have an aerodynamic diameter of less than ten micrometres. If the particulate matter in the air at a given place is less than ten micrometres the measurement of this particulate matter is referred to as PM10. Continue reading →

This week one newspaper reported that hydrogen based fuel would be available in a few years, it would be capable of using it in existing cars and would sell for about a third of today’s oil based fuel, provided the fuel was not taxed. If you factor in the tax that all governments now place on fuel, then the new hydrogen fuel would be considerably more expensive than fossil based petrol and diesel, but the news report glossed over this aspect.

Nature News reports that the ocean water that flows from the Arctic Ocean today is two degrees Celsius warmer than it has been for two thousand years. Fifty or so metres under the Fram Strait, between Greenland and the Svalbard Islands, is a warmer current which in Summer has a water temperature of 6⁰C, significantly warmer than the surface temperature of the Arctic which is usually in summer just below freezing point.

The European Union’s Emissions Trading Scheme remains suspended following revelations that Euros 30 million worth of certificates have been stolen and sold. There is no certain date when spot trading will begin again, so if you have emissions certificates that you wish to sell or certificates that you wish to buy, you cannot do so right now.

When the Romans first set foot in England they found a country that was virtually covered in trees. Apart from marshlands, which were subsequently drained, and grassy chalk down lands, forests were the prime feature of the English countryside. Today if you travel from London to the north along the M1 motorway it can be hard to imagine that great forests covered the countryside that you see today. By the time the Normans landed in 1066 the forest were still the predominant feature of the landscape. They were so large that outlaws could hide in them. The forests of England were deciduous woodlands, mainly oak. Continue reading →

Consumers often ask why they should pay for renewable heat. The funds allocated for this over four years may be around £850 million, which is a great deal of money in these hard times. Renewable heat in effect comprises biomass, solar thermal panels for heat and hot water and heat pumps. There are two main reasons for encouraging renewable heat. The first is to provide a measure of energy security, lessening the dependence on imported fuel. The second reason is to help alleviate rapid climate change because, biomass aside, these technologies emit significantly less carbon dioxide than traditional fossil fuel and in the case of solar panels they emit virtually no greenhouse gases.
Is it right that these installations should be incentivised by the taxpayer? I think so. Continue reading →

Today we are told that about four percent of the United Kingdom’s electricity is supplied by wind farms. We are told this by the Renewable Energy Centre who also tell us that the wind farms supply around 5GW of power; there are another 18GW of wind farms that are in the planning process and that there is potential to generate 49GW from wind energy, which is half the domestic power usage of the nation.
