Towards Tackling Power Shortages


Firstly, Sekuru Soko, we have to make sure that the available electricity from the grid is used strictly for industrial purposes. Our industries and essential services like hospitals must have constant supplies of electricity. This is for running critical equipment and machinery. Let us define these as primary usages. We will always need energy even for non-primary industrial activities. Like Sekuru Soko Brighton put it, muniscle wastage like unnecessary lighting, excessive cooking, et cetera do cumulatively lead to a massive wastage of electricity on non-productive or non-economic activities. In dealing with such energy usages, here are a few things we can do.

1. Let us encourage the use of solar electricity. We have enough solar energy we can tap for non-primary uses such as lighting and running light equipment such as radios and televisions. Farms, hospitals, schools and other institutional non-primary energy consumers can be powered using solar electricity.

2. For domestic or household-installed solar energy, each house is likely to generate more electricity than it can use. The surplus can be fed into the national grid for credit.

3. We have to come up with energy-saving policies that are actionable and with an enforceable regime of compliance rules. Conventional oven stoves have to be replaced with microwave ovens. I cook, kulez. I know it takes less time and energy to precook my nyama yekugocha using a microwave oven than boiling that nyama on a conventional stove. In 10 minutes, I can defrost & precook a pack of frozen meat. Lowering taxes on microwave ovens & increasing taxes electric stoves has to be considered.

4. There are fluorescent lights and light-emitting diodes (LEDs). We can phase out the stardard bulbs. Fluorescent lights and LEDs demand low energy but are efficient. Let us lower tariffs on these while jerking up the price on the wasteful ones.

5. There is plentiful natural gas on the region. We can use gas for domestic cooking. Rather than importing gas stoves, let us encourage, or even demand, our university & even vocational colleges to reverse engineer imported gas stoves. We can ask the private sector and creative citizens to enter into the challenge, too.

6. In the Highveld, we have mountains that cause atmospheric airflows. We can install wind turbines to generate energy. A few farms in places like MashCentral, MashEast & Manicaland can be used as models to assess the feasibly of generating electricity at the point of usage (POU).

7. On a larger scale than this, we can put wind turbines on the mountains surrounding Mutare for POU power generation. We have enough mechanical & electrical engineers to reverse engineer imported turbines. Our universities can lead this localization of equipment reproduction.

8. We must explore more POU power generation using gas turbines. Jet engines are now used to generate electricity with greater frequency due to vast supplies of natural gas. We must join the fray.

9. We have enough rivers that can be dammed for the dual purposes of supplying water and generating electricity. If we already do not have one, we must have an army corps of engineers. We have an idle standing army. Let us put it to work to uplift the nation in times of peace.

10. We have enough coal to generate electricity. Environmentalists will bewail pollution, but we will have to sacrifice something to revive Zimbabwe. Every industrialized nation has had to go through a dirty phase on it's way to economic development & prosperity. At any rate, there are now ample clean-coal power technologies to enable  us to use our vast reserves of coal. Again, this offers the opportunity of POU power plants.

11. We must not rule out nuclear energy to generate power. This need not be a national objective. Let it be regional. South African has a historical foothold on this. We have very bright personnel who can contribute to the regional venture.

12. Though it may sound like a quark, we may have to participate in basic research on fusion or implosion energy. We want to be at the forefront if ever this leads to cheap & plentiful energy in the future. Chew on these thoughts, muera Gudo.
