Small-scale technology can help women to raise their status and increase their income and education, says Henrietta Miers.

Climate Innovation Centers can promote clean technologies but need backing with a coordinated effort, says policy specialist Ambuj Sagar.

More Asia–Pacific countries need to embrace renewable energy and follow the first tentative steps of some governments, says Crispin Maslog.

Looking through a 'human rights lens' can improve S&T programmes, while S&T can help strengthen human rights work, says lawyer Jessica Wyndham.

Using the human rights framework to tackle challenging ethical questions can guide climate policy, argues political philosopher Simon Caney.

Technology transfer is a priority for a new phase in China–Africa cooperation — but it needs the right direction, says Linda Nordling.

Country-specific costing of scaling up renewable energy technologies can help allocate climate funds efficiently, says Michael Jakob.

Algal biofuels, like crops, demand land, water, fertilisers, pesticides and inputs that are costly for India, says Hoysall Chanakya.

Crispin Maslog says the region should follow the Philippines' lead and focus on renewable, not nuclear power.

Reforms in the Arab region should focus on transitioning to a green economy, argues award-winning environmental advocate Najib Saab.

Jeremy Rifkin says the developing world could leapfrog into a new energy era by merging communication and renewable energy technologies.

Business models that pair up cheap solar technologies with cell-phone services can provide the poor with renewable energy, says Carl Pope.

Desertec, an ambitious solar power project in the Middle East and Africa, should be more transparent and participatory, argues Athar Osama.

The two regions have much to gain from coordinating research and enhancing scientific cooperation on solar energy, says Frank Lehner.

Environmental engineers Tasneem Abbasi and S. A. Abbasi warn that widespread adoption of small hydro could repeat a history of environmental damage.

Biomass fuels are often branded dirty but can be harnessed in 'greener' ways through new technologies, says Duncan Macqueen.

To make an impact, small-scale renewable energy systems must fit social expectations and cultural norms, argues Benjamin K. Sovacool.

With the right support, small-scale hydropower could be a cheap and clean fuel for development, says energy advisor Teodoro Sanchez.

South Africa must get better at acquiring green knowledge and technology transfer — or be left out of global markets, says Radhika Perrot.
