Drs. Judith Cherni, Imperial College of London, interview in Havana about the next enviromental disaster .
the 2010 March 15 23: 21: 53 CDT , "Juventud Rebelde", Havana, Cuba.
The emission of gaseous pollutants in the generation of energy has upside down to the planetary climate, and is something on which there is no doubt. However, another point and curious is that climate change will also affect - already affects! - the production of energy.
The Dr. Judith Cherni, teaching of Imperial College London who presented an interesting presentation at the recent international meeting globalization and development issues, has investigated the matter: "Climate change affects, for example, courses from the water." Much of the energy produced in the countries of the South is hydroelectric power. As there is enough water, no problem, but by altering the climate change rainfall regimes and the rivers flow.
"Another aspect: the hurricane." Forecast more and more intense, by the sea temperatures rise. ' Then winds destroyed energy infrastructure and takes much time rebuild ".
-With the changes provided for in the course of the winds, the wind fields would have to be relocated?
-The relocation of any renewable system will be very important: wind regimes are changing, and predicted more variation. Also temperature, solar radiation, and this will have a direct effect on smaller and more renewable energy systems. Located in a place, but 15 years not produced perhaps the same amount of energy predicted today.
-As regards solutions compared to fossil fuels, mentioned much electric car...
-Yes, but it depends on where is that electricity. Fall much immediate pollution which cause the common car leads to basic questions: is a technological breakthrough, but if we want to worry about stopping climate change, we must think changing way of life. If we continue depending on more and more of the car, it does not change somehow energy dependence. It would take more collective transport, closest sources, i.e. an overview. The electric car is a temporary solution.
"Is also expensive car." They are an opportunity for the multinationals of the car. The wealthier are those who can pay. And another point: many people who today have an electric car, already have another car. To travel outside of the city, over long distances are employing fossil fuel. 'Then does not solve the problems that lead to this environmental disaster'.
-Are you favour the use of renewable energies in a hundred per cent, or a cocktail of these and, for example, nuclear power?
-If you could reach 20 per cent of renewable, it would be an achievement. A 40 per cent, a revolution, but it is very difficult. I think we should use all the energy, menu although my tendency is to prevent nuclear energy, the environmental risks and health involving.
-What views on "carbon sequestration" technologies?
-That are more advanced, but are not proven. They are expensive, require much research and investment, and there are several countries that already opt for them. They could solve the problem, but I don't know, impacts because we have no way of knowing what will happen to him 200 years to bury carbon. It is a risk. We must think in future generations.
-The European countries more contaminated by 2030, while its population will decrease. How do you explain this?
-Increase the ecological footprint, i.e. pollution per person: the amount of food, electricity, water consumed by each, and requires energy to be produced. Indeed, we are talking about places where energy efficiency is higher, however, emission levels are not going to get much as you would be expected.
'How?' Because there is, I repeat, a change in lifestyle. The luxuries are priced at the energy level. And I don't know if we can expect both a model change'.
El daño ambiental causado por el uso de fuentes de energía, repercutirá irónicamente en la producción de esta.
