TECHNOLOGY: Underwater Turbine looking new energy [video]

Verdant Power hopes to make foreign oil and energy pollutants a thing of the past by building six underwater turbines that convert current to energy. But first, they have to work out the kinks.

The operation, which only started in December, is currently under construction. According to reports, the strong currents are what are causing the damage to the turbines.

The company, its partners and state officials who have financially banked the project, are saying that this is only a setback and that the project will eventually be successful. Even after more money had to be poured into the project to repair damages, people involved in the endeavor were optimistic.

Mollie E. Gardner, a geologist for Verdant Power who owns the equipment, said, "But the good thing is that there's more power in the East River than we thought."

The project proved that the turbines can create 1,000 kilowatt hours a day of clean energy, according to reports. Now the mechanisms will be shut down until the company can figure out how to fix them.

Trey Taylor, the habitually optimistic founder of Verdant Power, said, "The only way for us to learn is to get the turbines into the water and start breaking them."

CLIMATE CHANGE: The nuclear energy is the solution for the present? [video]

Bruno Comby and Frédéric Marillier are both French environmentalists who believe global warming is real, dangerous, and has to be stopped. But Marillier heads the anti-nuclear campaign of Greenpeace France.

He advocates renewable energies rather than a nuclear industry that he argues is expensive, dangerous and unreliable. Bruno Comby is president of Environmentalists for Nuclear Energy.

He believes nuclear power is needed to help reduce co2 emissions and that global warming poses a bigger threat than nuclear catastrophe. Two different approaches to saving the planet now, in Agora.

EUROPA: Nuevas necesidades Nuevos desarrollos tecnologicos para los navios [VIDEO]

Air Cavity System
Reducir la polución de uno de los más grandes contaminantes --los buques cisterna y otros barcos-- gracias a un nuevo invento danés.

Air Cavity System es un cojín de aire que se sitúa entre el agua y el casco del barco.

Buques con motores menos contaminantes
Una nueva generación de motores para la navegación está a punto de aparecer. Europa tiene un 40% de la flota mundial, por lo que es de vital importancia hacer barcos menos contaminantes, más económicos y fiables.

Además con el incremento del tráfico marítimo en las zonas nortes del Mar Artico, es el momento de asentar las reglas para navegar en este área.

EUROPA: La energía para el futuro, eL Hidrógeno [VIDEO]

El HIDROGENO, es el elemento químico de número atómico 1 y símbolo H. A temperatura ambiente se lo encuentra como hidrógeno diatómico, un gas inflamable, incoloro e inodoro, y es el elemento químico más ligero y más abundante del Universo, estando las estrellas formadas mayormente por este elemento en estado de plasma durante la mayor parte de sus ciclos.

Aparece además en multitud de sustancias como, por ejemplo, el agua y los compuestos orgánicos, y es capaz de reaccionar con la mayoría de los elementos, es el elemento más abundante en la naturaleza.

El núcleo del isótopo más abundante está formado por un solo protón. Además existen otros dos isótopos: el deuterio (tiene un neutrón) y el tritio (tiene dos neutrones).

Los combustibles fosiles se usan, actualmente, para cubrir casi todas las necesidades energéticas. Pero es necesario encontrar una alternativa.

El hidrógeno puede ser la respuesta siempre y cuando se logre producirlo de una manera limpia y respetuosa con el medio ambiente.

La solución a este complejo problema está, quizás, en el proyecto europeo Hydrosol.

BRASIL: Brazilian biofuel beckons Europe [video]

Brussels sees Brazil as a key player in the fight against global warming. With the tenth largest economy in the world, Brazil is home to most of the Amazon rainforest. It is a major producer of biofuels. President Lula da Silva is due at a conference in Brussels this Thursday where the main goal will be to foster consumption and production of fuel made from crops. EU leaders agreed in March to boost the role of biofuels, with a clear deadline.

Christian Bergsmuller is a member of the EU delegation in Brazil: "If the EU (has) that ambitious agenda of moving to about 20% of renewable energy by 2020 - which is very ambitious - we know that we have to import from other parts of the world, and Brazil will certainly have a stake in our energy mix in the future."

In the future, if trade and investment end up predominantly bilateral, this risks complicating business dealings further afield. Brazil is the EU's main trading partner in Latin America but broader interests cannot be ignored.

Analyst Mario Telo in Brussels says Europe is learning from previous experience with other major South American players: "The probable result will be to reinforce Europe-Latin America ties following on from the continent's number one country. The risk is that an individual partnership with Brazil might create difficulties in relations with other Latin American partners. The one-on-one approach proposes a bilateral model such as exists with Chile and Mexico. The Portuguese EU presidency wants to avoid this danger."

With 188 million people, Brazil is a land of huge contrasts - the better-off playing while the slum-dwellers stagnate. Newly-stable Brazil is looking towards Europe to reinforce its international prospects to help bring benefits to the poorest places.

Nuclear vs Renewables

French nuclear and other energy sources no longer clash. On the outskirts of Paris, this subsidised housing block has solar panels on the roof. A renewable energy NGO called CLER manages the initiative, in a country where nuclear power provides a significant portion of the overall needs. Renewables in France represent less than six percent of the whole -- about the EU average.

La Nuclear vs Las Renovables

A las afueras de París se encuentra el barrio de viviendas sociales más grande de Francia con capacidad para producir energías renovables. En los tejados, paneles fotovoltaicos captan los rayos solares de la capital francesa. La iniciativa está gestionada por CLER, una ONG que intenta promover la utilización de nuevas energías en Francia.
