Back-up Generators: A sustainable Power Solution?
Over the last decade, South African households have been compelled to look for short-term solutions to circumvent the recurring energy blackouts because of a failing functional electricity grid.
High sales numbers suggest that back-up generators, used in combination with solar panels, are being sought as a popular new global solution. What makes this concept so attractive, is the associated once-off cost, energy independence and the easing of overdependence on the traditional grid. Although rising in adoption, generators, still provide a considerable number of drawbacks, with emissions of harmful gases such as carbon monoxide and nitrous oxide providing reason for concern. Another problem that homeowners tend to overlook, is the obligation to install, refuel and maintain a generator. It is not advisable for generators to be connected and installed by anyone, other than a certified electrician.
Modern utility technologies have been a highly debated topic for some time as technology competes to be the ‘next best thing’. However, the fact remains that the use batteries is seemingly becoming the most viable long-term energy storage medium, already accessible. Unfortunately, most battery storage projects currently underway are focused on short-term energy storage and not built to handle the capacity of the traditional grid. Limited storage has therefore not resulted in adaptation; thus, many individuals remain dependent on generators and renewables along with the power grid as primary source.
The growing trend to adopt solar energy generation is one way to reduce carbon emissions, but still creates new challenges involving the supply variability of the power source. Most obviously, the sun only shines during the day. Power source variability will remain for as long as the traditional grid struggles to meet peak demands. As the growing population strives for more efficient and sustainable energy strategies, the challenge remains that additional resources will be required. The implementation of renewable energy solutions and installations of infrastructure such as generators, are only the first step to a sustainable future.
To conclude, generators, although effective remain a temporary solution, one which should be used sparingly as a worst-case scenario. Local homeowners and businesses alike are encouraged to consider adopting alternative back-up power options to cater for long term autonomous power storage solutions.
