not all gold that glitters (often mercury )

In the field of environmental research and sustainability, often, for every innovation, initial euphoria, followed by a disappointment. Remember
unleaded fuel and its benzene, and catalytic converters that only work well over long distances, while in the urban cycle rarely reaches operating temperature?

Now is the time of low energy light bulbs, fluorescent lamps: These lamps

base their operation on mercury, which according to EU Directive 2002/95/EC should not exceed 5 mg per lamp. But reducing
or eliminate mercury requires costly research programs, instead are able to manufacture all with so much mercury.
So while companies tout as the Dutch Philips lamps that contain a lot less, in Italy there was a huge spread of lamps of low quality and high mercury content, thanks to the rich "green certificates" that are acquired through the free distribution of lamps (of course, this is preferable to use low cost).

These lamps are environmentally friendly bombs, especially in Italy where nobody took the trouble to inform the public that the fluorescent faulty can not be thrown into the glass or, worse, indifferentiation.
They must be disposed of without breaking them, the materials WEEE. (Collection Electrical Appliances Electronics), it can be delivered to the dealer or to delegate to municipal landfills. (The ecological oasis of Manchester, under the shed, has bins WEEE)

Another disappointment is then the fact that these energy saving light bulbs instead of reducing electrical consumption, have increased artificial illumination, with effects disastrous night light pollution. Unfortunately
fact, in the absence of widespread environmental awareness, the technical measures for reducing consumption are incorporated users only as an opportunity to further waste on the cheap.

CO2 from nuclear and solar

Pour into the atmosphere as CO2 produced by a KWh generated by fission or a solicitation of a ray of sun at a solar cell? If they are asked
American scholars Vasilis M. Ftenakis and Hyung Chul Kim, who analyzed the whole chain that leads to the generation of electricity in two cases with nuclear power and photovoltaics.
The photovoltaic power generation and nuclear need tools. In the first case the device is the prince nuclear reactor consists of bars of enriched uranium contained in a large building called Central in the second panel of silicon supported on the ground or on a roof.
Neither is born out of nothing. Both are the product of a production chain that starts from raw material (ore containing uranium for nuclear power and waste of silicon for the photovoltaic industry microeletttronica) and, through various stages of processing, the finished product.
Regarding nuclear power, the stages of production include the 'extraction of ore containing uranium, the pulverization and separation from the dross, the enrichment of uranium-235 isotopes, the production of enriched uranium fuel rods, construction and dismantling the central and treatment of nuclear waste.
For photovoltaics, the silicon melts scrap the production of microchips and build the panel should be located and then eventually dismantled.
The two researchers concluded that the source of nuclear energy produces more greenhouse gases between 22 and 49 g. CO2-eq/KWh (on average) for nuclear and 17-39 g. CO2-eq/KWh for solar photovoltaics.
Just this awareness to reflect upon the nuclear option?
Maybe not, but it is a matter to be taken into account.
