Renewable energy capacity overtakes coal

By | Article | No Comments

The International Energy Agency says that the world’s capacity to generate electricity from renewable sources has now overtaken coal.

The IEA says in a new report that last year, renewables accounted for more than half of the increase in power capacity.

The report says half a million solar panels were installed every day last year around the world.

In China, it says, there were two wind turbines set up every hour.

Renewable energy sources, such as wind, solar and hydro are seen as a key element in international efforts to combat climate change.

At this stage, it is the capacity to generate power that has overtaken coal, rather than the amount of electricity actually produced.

Renewables are intermittent – they depend on the sun shining or the wind blowing, for example, unlike coal which can generate electricity 24 hours a day all year round.

So renewable technologies inevitably generate a lot less than their capacity.

Even so it is striking development.

The IEA’s Executive Director Fatih Birol said “We are witnessing a transformation of global power markets led by renewables”.

Besides for the tremendous savings, the annual generation carbon savings is equivalent to:

  • 2005 tree seedlings grown for ten years, or
  • 2742 incandescent lamps switched to LED’s, or
  • 6 tons of waste recycled instead of landfilled, or
  • 300 000 km travelled by car

We want to congratulate Hugenote for having the vision to create this lasting legacy.

Eskom’s holding us hostage – again

By | Uncategorized | No Comments

Demanding an end to private power producers damages the economy – again.

Mike Schüssler | 26 July 2016 00:02

The International Monetary Fund’s (IMF’s) latest annual assessment of our economy is blunt and highly critical of some economic policies, as well as the management and performance of State-owned enterprises (SOEs).

The IMF wants more competition in the South African economy and in the labour market. The IMF and rating agencies have also long pointed to SOEs’ big influence on the economy – by creating growth bottlenecks and their insatiable need for government guarantees when they expand capacity.

David Lipton, first deputy managing director of the IMF, speaking at Wits Business School, said: “Then there is the matter of State-owned enterprises. They play a crucial role in the economy, but they are plagued by inefficiencies, poor management, and weak balance sheets.… Moreover, the private sector is unable to enter key sectors dominated by SOEs. This only fortifies the bottlenecks in the economy.”

A few days later Eskom announced it no longer wished to buy more power from independent power producers (IPPs). Read More

In this article, we look at the rise in electricity costs, the immediate outlook into the future and the role of Renewable Energy.

Early in November, Eskom submitted an application to the Energy Regulator (NERSA) to retrieve unrecovered revenue for the 2013/2014 financial year from the Regulatory Clearing Account (RCA). The application was done to recover R22.8 billion applicable to this period.

If approved, this could potentially mean an increase in tariffs of up to 17% from the 1st of April 2016.

Eskom further indicates that there will be another submission to address the shortfall on the 2014/2015 year. This means that the impact of higher increases, will be felt beyond next years increase.

The percentage NERSA approved was 8% per year until the 2017/2018 financial year, however, NERSA already deviated from this by granting a 12.69% for the 2015/2016 year. This was on the merit of recovering R7.8 billion in costs.

As a quick comparison, if a R7.8 billion recovery led to a 12.69% increase, then it would be fair to make the assumption that a R22.8 billion recovery would lead to a greater increase than the 12.69% granted for the current financial year ending March 2016? Read More
