Sustainable Energy Roadmaps | Worldwatch Institute | Développement durable et efficacité énergétique | Scoop.it

Transitioning from a carbon-intensive economy to a low-carbon future presents challenges and opportunities for developing countries. The Sustainable Energy Roadmaps help countries successfully navigate the change to an infrastructure capable of meeting the energy challenges of the 21st century.


The approach examines a country’s potential for renewable energy production such as wind, solar, small hydropower and biomass. Existing energy infrastructure is analyzed to identify the potential for, and hurdles to, increased efficiency and energy storage. At the same time, current socio-economic and policy environments are factored into the analysis to identify barriers to low-carbon development and determine international best practices to suggest how they can be overcome. Equally important, funding options that might be available from private, public, and multilateral institutions to help bring renewable energy projects into being are assessed.

The project strengthens government and civil society capacity, enhances stakeholder engagement, and advances policies that combat climate change...

Some US states need to follow this roadmap!

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over | Développement durable et efficacité énergétique | Scoop.it

At the moment, wind power supplies about 4.1 percent of electric power in the United States. Still a bit player. Yet there’s a whole lot of untapped wind left in the world. Wind whipping through the Great Plains. Wind gusting off the shores. Wind circulating high up in the sky. So what would happen if we tried to harvest all of that wind?

 

We’d have enough energy to power the world. At least in theory. A new study published this week in Nature Climate Change finds that there’s enough wind potential both on the Earth’s surface and up in the atmosphere to power human civilization 100 times over. Right now, humans use about 18 terawatts of power worldwide. And, technically, the study found, we could extract about 400 terawatts of wind power from the Earth’s surface and 1,800 terawatts of power from the upper atmosphere.

 

Even the most optimistic near-term projections for wind power, however, tend to be more restrained. In 2008, the U.S. Department of Energy released a comprehensive report estimating that wind power could provide, at most, 20 percent of U.S. electricity by 2030. And for that to happen, the cost of wind power would have to keep plunging, the number of turbines built would have to steadily increase by about 14 percent each year, and utilities would have to build new transmission lines to accommodate the extra energy.

Renewable Energy Realities: US Energy Transparency Infographic

Renewable Energy Realities: US Energy Transparency Infographic | Développement durable et efficacité énergétique | Scoop.it

Renewable energy enjoys broad support in the US where people expect the government to support emerging clean power technologies- Americans more concerned about the state of the economy than the threat of climate change: 41% of respondents ranked climate change in the lowest category as a threat facing the world and 51% ranked the economic recession in the highest category in the recent 2012 Global Consumer Wind Study.

When asked to what extent does the electric utility industry cause human-action induced climate changes, 32% of GCWS respondents answered to a certain degree and 39% answered to a high or very high degree.

The overwhelming majority (67%) of respondents said that they would prefer to have their electricity sources supplied by renewables, versus 9% for fossil fuels and 8% for nuclear.

78% of respondents said that they would prefer to see renewables such as wind, solar, hydro, biomass and geothermal developed over the next five years.
