Mini-grids and off-grid investment crucial for energy access in Africa (downtoearth,)

Majority of Africa’s population still lives without electricity or connection to the grid. As a way to pull them out of darkness, a new report released by Africa Progress Panel (APP) advocates for investments in mini-grid and off-grid connections.

Almost two-thirds of Africa’s population or 620 million people do not have access to electricity, and unless the electrification rate increases, another 45 million individuals will be added to this by 2030. The continent is not just mired with lack of access, but also a deficit of power, the report says. To give a scale of difference, the average American consumes over 13,000 kilowatt hours (kWh) of electricity a year and the average European somewhat less. The average African (excluding South Africa) uses just 160kWh.

While it seems logical to focus on big projects such as large dams and power pools that will scale up national and regional infrastructure to solve the energy crisis, these projects are expensive, complex and slow to implement, particularly in rural areas, highlights the APP report. As the costs of renewable energy sources fall, Africa should leapfrog into a new era of power generation similar to its advancement in telecommunication, it suggests.

Using off-grid technology will be crucial for energy access in the continent, the report marks. Off-grid solar photovoltaic (PV) systems are now the most economical sources of electricity for more than one-third of the African population who lack access to electricity, the report argues. It says that most Africans live off the grid or with unreliable grid access.

While post popular off-grid products are solar lanterns and mobile chargers, higher-end products like solar home systems are gaining popularity in the dynamic market. Solar power also reduces the economic burden of energy on the poor. Comparing costs, the report says, high-priced and low quality energy from candles, batteries and kerosene can be replaced with renewable sources.

Off-grid solar can also be used to power farms and small enterprises, as per the report, nearly 50 per cent of which identify inadequate access to electricity and poor quality of supply as serious constraints to production.

Grid-based electrification in the continent is slow, and the report suggests mini-grids to supplement centralised supply. Mini-grids comprise of an electricity generator and a distribution network that can cater to several users, such as households and businesses. The International Energy Agency (IEA) estimates that 140 million people in Africa will gain access to electricity through mini-grids, yet unlike off-grid solutions, the promotion of mini-grids appears to lag.

As per the report, they can provide electricity in rural and remote areas, where populations are dispersed and per capita electricity consumption is low, at much lower cost than central grid extension. They require smaller capital investment than grid expansion, making it easier to secure finance.

The report also asks for policy reforms for quicker electrification and investment in this multi-layered approach.

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”.

The Supreme Court on Friday came close to ordering the government not to deport the Rohingya.

It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests.

The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach it in …

Khar’s experimentation with Himalayan nettle brings recognition (downtoearth)

Nature never fails to surprise us. In many parts of the world, natural resources are the only source of livelihood opportunities available to people. They can be in the form of wild shrubs like Daphne papyracea and Daphne bholua (paper plant) that are used to make paper or Gossypium spp (cotton) that forms the backbone of the textile industry.

Nothing can compete with the dynamism of biological resources. Recently, Girardinia diversifolia (Himalayan nettle), a fibre-yielding plant, has become an important livelihood option for people living in the remote mountainous villages of the Hindu Kush Himalaya.

There is a community in Khar, a hamlet in Darchula district in far-western Nepal, which produces fabrics from Himalayan nettle. The fabric and the things made from it are sold in local as well as national and international markets as high-end products.

A Himalayan nettle value chain development initiative implemented by the Kailash Sacred Landscape Conservation and Development Initiati…

The Chipko movement as it stands today

The idea behind the Chipko movement originated in early 1970s from Mandal, a village in Chamoli district of Uttarakhand. Forty-three years later, Down To Earth travelled to Chamoli and Tehri Garhwal and spoke to the participants of this movement about its relevance today
