The recycling industry for electric car batteries is slowly taking off, but it is difficult to get car manufacturers to use recycled materials. Generally, people have the impression that recycled material is not as good as new material. The results of a new study show that batteries with recycled cathodes can be as good or even better.
Considering that nearly 50 percent of African countries' export value is fossil fuels, the global energy transition may have profound implications for the economies of these countries. In an effort to accelerate the development of renewable energy, many African countries have introduced policies to promote renewable energy.
A new study has found that only 50% of the world's roofs would need to be covered with solar panels to meet the world's annual electricity needs.
Asia, North America, Europe are potential hotspots for rooftop solar power generation. Storing solar power is expensive, so it can be difficult to use solar efficiently in areas with varying conditions.
The floating PV pilot project, established at the Kraaifontein Municipal Wastewater Treatment Plant, includes a floating PV system and a ground-mounted PV system to determine the evaporation savings and relative energy generation performance of the floating PV technology.
French company Tractafric has commissioned a 7.5MW battery storage system for the 74.5MW microgrid at the Kibali gold mine in DR Congo. The battery system, which is equipped with inverters from Caterpillar, was combined with a remote monitoring system. Caterpillar expects to reduce diesel consumption in Kibali by 3 million l/year.
Nigeria undoubtedly has the largest number of start-ups in Africa, but how well do these companies perform? Many claim that the government is not tech-friendly, others that the startups are not competent enough. However, research shows that treating employees is the biggest challenge in technology companies.
Touted as a model for a sustainable future, this idyllic hilltop village north of Dar es Salaam is using environmentally friendly technologies such as solar, wind, biogas and other modern technologies to reduce its ecological footprint.
In Nigeria, the over-reliance on fossil fuels (oil and gas) as the main source of revenue gives the careful observer cause for concern as to whether the country is ready to keep up with global pressure to transition to renewable energy. According to OPEC, petroleum export earnings in Nigeria currently account for about 86% of the country's total export earnings.
Accelerated expansion of renewables should also be accompanied by global commitments to ensure that they do not leave a toxic legacy that disproportionately affects developing countries. The circular economy is a promising way to address the problem of solar e-waste.
