Tapping Renewable Resources

Removing reliance on non-renewable energy sources through solar water heaters is a promising and cost-effective approach to mitigate the impact of over-reliance on fossil fuels. The growing concern about climate change and scarcity of fossil fuels has directed the world towards renewable energy.

Solar water heaters, a type of renewable heat system, use sunlight to heat water for various purposes including hot water generation. This renewable energy is considered an attractive solution for global energy challenges as it requires low operational costs, can provide hot water during on-site generation, and can be easily scaled up or down in terms of power and capacity.

A well-designed thermal energy system consists of a heat exchanger a circulating pump a circulating pump and a storage tank. The heat exchanger is the key component of the system, absorbing and converting natural heat into thermal energy. The solar water heater works in two cycles: the absorption cycle and the cooling cycle. During the absorption phase, the heat exchanger heats the water in the storage tank, and in the off-peak phase, the hot water is pumped into the industrial facility for actual use. Conventional absorption heat pump water heaters also improve efficiency by using a second heated fluid to heat the system whenever possible.

Implementing large-scale solar water heater systems can significantly reduce the global electric power demand. Data suggests that, for every 1 MW of solar water heater capacity installed, the demand for electric power from energy providers is decreased by at least 0.7-1.4 MW.

In emerging markets, such energy-efficient technologies can save residents a significant amount of money on their energy costs.

It is estimated that global implementation of solar water heaters could reduce global electricity consumption by 12-18% by 2050, saving over $1.1 trillion in electricity costs.

With such truly beneficial advantages associated with solar water heaters, regulators worldwide should prioritize and invest significantly in developing solar water heater technologies, providing support for production and large-scale deployments.

However, current energy sectors are lacking the competitive pace on renewable energy sources, driven primarily by the development and marketing of solar photovoltaic (PV) technology. Regulators must therefore provide prompt attention and subsidies to renewable energy sectors, besides focusing on reducing administrative burdens for entrepreneurs to step into the commercial energy markets.

Increasing the demand for solar water heaters will also heighten job opportunities worldwide, and push down compensation in renewable energy industries while increasing growth prospects among the companies in this area. So the deployment of solar water heater technologies will undoubtedly prove pivotal for saving global electric power demand and making a significant dent in solving one of our most enduring energy challenges.
