Many people argue that Hydrogen is not an energy source but an energy carrier. Hydrogen is certainly an energy source by itself but is to be derived from other primary sources such as water or natural gas because is not available in a free form.
Generation of Hydrogen from its sources require an additional energy but when such an energy is provided by renewable sources such as sun, wind and sea then the cost becomes secondary in the long run.
Therefore, battery may not be able to compete with hydrogen in the long run though it provides a temporary solution to pressing power problems in short term.
Moreover, batteries rely on materials like Lithium whose availability is limited even though they are recyclable.
Eco cities have a huge opportunity to impact the magnitude of climate exchange: after all, larger cities are consuming two thirds of the world’s energy and responsible for emitting over 70% of global CO2 emissions.
We analyzed the key objectives of the top 10 eco cities that were ranked highest in terms of environmental sustainability. Read More
The City of Los Angeles took a significant step toward realizing its global leadership potential. Mayor Garcetti released LA’s first-ever urban sustainability plan: the pLAn.
LA City Council members Paul Krekorian and Mike Bonin coauthored legislation for a fast route to 100% renewables for LA. With an appreciative nod from the Sierra Club, the news reported at 11district.comfollows:
“LADWP is on the verge of making significant investments in its infrastructure, and with that 100-year-old power system in need of significant upgrades, the city has an opportunity to re-create its utility in a way that recognizes the potential for a fossil-free future, demonstrates global leadership in its commitment to clean energy, and protects ratepayers from the increasing costs of carbon-based fuels.”
Under the current plan, emissions are expected to drop. Under a new plan, they could drop to zero!

London Mayer Boris Johnson, made a deal with Toyota, bringing 12 hydrogen cars to the UK Capital by the end of 2015
Boris Johnson, mayor of London, announced that some of the world’s most advanced new hydrogen cars will come to London. He is promoting the cleanest, greenest, energy technology for the future of transport and infrastructure in the capital.
Johnson: “It’s tremendous to drive the hydrogen powered Toyota.”
Toyota made a deal to deliver 12 brand new Mirai hydrogen powered vehicles to London. Four will be taken on by Transport for London to assist with essential engineering and maintenance work carried out between bus stops and Tube stations.
The Mirai is the first hydrogen fuel cell sedan vehicle to be commercially mass produced. By the end of 2015,all 12 of the vehicles will be driving in London, used by private hire fleets and green minded businesses.
From 1950 to 1980 the number of people living in favelas in Rio de Janeiro alone increased from about 170,000 to more than 600,000, and by the early 21st century it was estimated that there were as many as 1,000 favelas there.
Given the rate of change, our world will be a very different place by 2040. More and more people are moving to cities.
How will billions of city-dwellers access what they need without putting intolerable strains on the planet?
How can we plan now for more sustainable ways of life in a radically different world?
