Who is building new nuclear power plants?

juerg — Sat, 13 Sep 2008 13:47:08 +0200

There has been a lot of talking about the renaissance of nuclear power in the light of global warming and increasing oil prices. So let's have a look at the global situation: Who is building new nuclear power stations and who is just talking about?

Eat less meat: CO2 emission of our food

juerg — Sun, 07 Sep 2008 18:55:03 +0200

The carbon dioxide emissions (carbon footprint) caused by our personal behavior is driven to a large extent by the type and quality of our nourishment. The amount of greenhouse gases caused by the production of food is different from one food type to the other (see table below). Worst is meat and in particular beef.

A environmental friendly and climate change friendly nourishment is characterised as follows:

Plastic bags and plastic bottles - CO2 emissions during their lifetime

juerg — Fri, 22 Aug 2008 17:53:14 +0200

A number of people have asked about the implications of using plastic bags on the personal carbon footprint as well as on the environment in general. There are some comparisons between paper bags and plastic bags available which clearly show that it all depends on how many times these plastic or paper bags are being used.

Littering is probably the severest problem related to plastic bags. Nevertheless let's now have a look at the carbon dioxide (CO2) emissions for the production and incineration of plastic bags.

Are cows the cause of global warming?

A cow does on overage release between 70 and 120 kg of Methane per year. Methane is a greenhouse gas like carbon dioxide (CO2). But the negative effect on the climate of Methane is 23 times higher than the effect of CO2. Therefore the release of about 100 kg Methane per year for each cow is equivalent to about 2'300 kg CO2 per year.

Olkiluoto: Finlands new nuclear power plant

Finland's Olkiluoto nuclear power plant: The Olkiluoto construction project in Finland is rapidly becoming an example of all that can go wrong in economic terms with nuclear new build. It demonstrates the key problems of construction delays, cost overruns and hidden subsidies.

CO2 emission of electricity from nuclear power stations

How much CO₂ is produced by atomic energy?

One of the few pros of nuclear power is the relatively low emission of carbon dioxide (CO2), one of the major causes of global warming. For this reason, it has been proposed as "the" method to mitigate the effects of climate change. However a recent life cycle analysis showed that nuclear power produces 4 to 10 times higher CO2 emissions per kWh electricity than renewable energies.

Cost of electricity from new nuclear power stations

juerg — Fri, 04 Apr 2008 17:56:35 +0200

Current discussions about possibilities to mitigate the effects of global warming have also opened discussions about a potential revival of nuclear power. In this context, it is often argued with very low cost of electricity from nuclear power plants. This seems to be one of the strongest arguments in favor of atomic energy. To determine the future cost of electricity from nuclear power, the cost from currently operating power stations is taken into account. This is not correct, however.

Europeans attitude towards the environment

Summary of Eurobarometer survey published on March 13, 2008. The report shows that Europeans are increasingly aware of the role played by the environment in their daily lives. More than 95% of European citizens feel that it is important to protect the environment. Some 80% also feel it influences their quality of life and consider that they have a role to play in protecting it. Climate change (global warming) tops the list of Europeans' environmental concerns, followed by pollution and man-made disasters.

A majority are also uneasy about the use of genetically-modified organisms (GMOs) in agriculture.

Water scarcity and global warming

juerg — Tue, 18 Mar 2008 11:40:04 +0100

With continued population growth, increased per capita consumption, and anticipated climate change, the global water situation appears bleak. Since water scarcity is a highly localized issue determined by regional climatic and demographic factors, a single solution will not solve all of the world's water scarcity problems.

However, improved management, more water efficient technologies, and support for the world's most vulnerable countries and ecosystems will likely play leading roles. According to the UN-backed World Commission on Water, coping with water scarcity will require global investment of $100 billion per year. Willingness to invest this sum will be vital to the future of human well-being and economic development in all countries of the world.
