When using wind or solar energy in off-grid situations some kind of energy storage is often needed.
A team of scientists have been working on a recycling technique in which they use lead, taken from used batteries and extracted at lower tempritures to make a new class of solar-electric panels.
One downside is that the material contains a small amount of lead. Extracting lead from ore is a high-temperature, polluting process that creates lead vapor and dust that's difficult to contain, the MIT researchers note. And if companies begin to produce perovskite solar cells at large volumes, the materials they would be mining and processing could become a serious health or environmental hazard, they say.
In other news there are also improving solar-themal (heat) energy storage to make it possible to store heat energy into electrical energy to power cars. The aim is to reduce the energy burnt in power plants that rely on coal or gas burning carbon fuels.
Both of these developments would be an amazing development for Nigeria in acheiving energy production levels that would also improve the overall health, reducing exposure to toxic chemicals being released from informal recycling in open areas (burning batteries) and also reducing the dumping of bad batteries on developing nations.

There is a wave of construction sweeping the continent. The construction of renewable energy generation plants.
Will this be the furture or a passing fashionable trend? Some investors have strong hope in hydroelectric dams in this regard.
But is it enough to sustain the energy needs alone? (Read on)
These maps present an assessment of how Africa’s electricity generating industry will develop in the next six years. They are predominantly based on schemes that are either under way, or have received funding, although in some cases, such as Nigeria and Cameroon, we have taken an optimistic view of the government’s stated target.
Ghana The government has plans to double Ghana’s generating capacity to 5GW by 2016. Among the schemes in progress is the $400m, 155MW Nzema solar plant, the largest in Africa. This is being developed by UK company Blue Energy. There is also a lively debate in the country about whether to build a nuclear plant.
Nigeria The government is targeting a massive expansion of generating capacity, from 5.9GW to 40GW. There is some scepticism about this figure, however, and observers have suggested that, given Nigeria’s record of public maladministration, it is unlikely to get much beyond 8GW. One indicator of Nigeria’s eventual success is the progress of the 3GW Mambilla Dam, a scheme first proposed in 1982. After murky negotiations with a number of Chinese firms and a meeting between presidents Goodluck Jonathan and Xi Jinping in May, a consortium led by Sinohydro is to carry it out. According to the Nigerian press, work on site is to begin in October.
These goals are a modest start to a massive energy deficit badly needed to stablise the economies of these countries. While some arelooking to expand some of the power plants using coal and other carbon releasing resources. Others are moring more towards cleaner and renewable resources.

Energy issues are as fascinating to see going the same way technology management is being taken care of in West Africa.
Keeping customers happy should not be only in focusing on the astethicsof the outcome but the quality of the work.
Moving customers to new technologies is not an easy challenge we undertake at CREEDS Energy Limited, but an ongoing project to educate and inspire innovation in the long term to how businesses try to acheive their own goals by getting them to see problems as opportunity. Modernising can be uncomfortable if one is not prepared the right way to accept the inevitable need of changing habits.
The news for these tech-laggard businesses only gets worse. Of course the same next generation of workers are also the next generation of consumers. They travel, have cool and expensive outdoor hobbies, are getting engaged and married, buying houses, having children – all requiring goods and services from small businesses. Many of these consumers will also become young entrepreneurial business owners – running truly "modern" small businesses - seeking B2B services. CCH Australia Ltd recently conducted a survey of 1000 small and medium business owners from which the results illustrate this is already top of mind for young business owners. Half of the respondents indicated they would consider replacing their accountant – traditionally one of the most trusted advisors to a small business – if he/she didn't move to a modern technology platform. More importantly, in the context of my thinking, when drilling in to the 18-34 year old age bracket the proportion was close to three quarters!
Three out of four young business owners are willing to abandon what's traditionally been the most trusted business advisor simply because of old technology! For me that's evidence of a fundamental shift in the importance of technology as a measure of a company's culture, what it stands for and where it's going.
Innovation in Africa is making small gains through small sector business growth in Nigeria, being ranked as the largest African economy doesn't automatically indicate most efficient. So we'll keep working hard to push for a sustainable economy from the bottom up!
