Renewable Energy Technologies: Top 5 Affordable Options For Sustainable Energy Solutions For a Greener Corporation

Adopting renewable energy technologies is a strategic move for corporations, as it is more cost-effective than one might think and assures stability in the volatile climate of fossil fuels. Here we list the top 5 affordable options for clean and sustainable energy sources that any business can choose from. Pick your industry and we can suggest a solution. We have carefully researched industry power requirements and suggested a solution to help you move towards energy efficiency in your business.

It’s crucial to consider the energy industry, green energy solutions, the availability of renewable energy equipment in South Africa, and research what is happening in the sustainable energy sector when making these decisions.

We have also included practical steps that we, at Effective Energy Consultants, follow to implement new systems for our clients. These steps should be something you look out for when choosing a sustainable energy consultant. 

Here are the top technologies for a greener corporation: 

1. Solar Photovoltaic (PV) Systems

Solar energy is one of the top choices any business should look into. It is cost effective in the long term and can be support any energy demand. In our opinion, it is the future of energy. 

Overview: Solar PV systems convert sunlight directly into electricity using panels typically installed on rooftops or ground-mounted arrays.

Affordability: The cost of solar panels has plummeted over the past decade, making it one of the most accessible and cost-effective renewable technologies. Incentives like tax credits, rebates, and solar sustainable energy certificates (SRECs) can further reduce upfront costs.

Benefits: Solar PV offers predictable electricity costs, potential savings on energy bills, and a strong sustainability profile that enhances brand image, and protects business against damages caused by prolonged power outages. 

Industry: Manufacturing, Retail, Information Technology and Data Centers, Healthcare, Education

2. Wind Turbines

Overview: Wind turbines harness wind energy to generate electricity and harness green energy form nature. Small-scale wind turbines can be an option for corporations with enough space and located in windy regions.

Affordability: While upfront costs can be significant, tax incentives, grants, and the decreasing cost of wind technology contribute to making wind power a viable option for corporations. Power Purchase Agreements (PPAs) also allow companies to invest in off-site wind projects at competitive rates.

Benefits: Wind energy is clean, abundant, and offers a hedge against conventional energy price fluctuations.

Industry: Manufacturing, Agriculture, Transportation and Logistics

3. Solar Thermal Systems 

Overview: Solar thermal technology uses sunlight to generate heat, which can be used for water heating, space heating, and industrial processes.

Affordability: Solar thermal systems can be more cost-effective than photovoltaic systems for heating purposes, especially in industries with high hot water or process heat requirements.

Benefits: Reduces reliance on fossil fuels for heating, lowers energy costs, and significantly reduces carbon emissions.

Industry: Manufacturing, Hospitality,

4. Biomass and Biogas

Think cows! any industry that deals or trades in livestock should look at natural gas options 

Overview: Biomass energy is produced from organic materials (wood, agricultural residues, or waste). Biogas is generated from the anaerobic digestion of organic waste, which can be used for heating, electricity generation, or as a vehicle fuel.

Affordability: Biomass and biogas projects can benefit from low-cost feedstocks, especially where corporations can utilize waste products from their operations or local agriculture.

Benefits: Provides a way to handle waste efficiently while generating energy, can significantly lower operational costs, and helps in achieving zero waste goals.

Industry: Manufacturing, Agriculture

5. Geothermal Heat Pumps

Overview: Geothermal heat pumps (GHPs) use the stable temperature of the earth to provide heating, cooling, and hot water for buildings.

Affordability: High efficiency and low operational costs make GHPs a cost-effective option over the long term, despite the higher initial investment. Various incentives can also offset the installation cost.

Benefits: GHPs offer significant energy savings, reduced greenhouse gas emissions, and minimal maintenance costs.

The EEC Process: 

Step 1 : Energy Consumption Audits

A combination of sophisticated tools is used to gather preliminary data on your location, such as climate, irradiation levels and available roof or ground area; a site visit is then undertaken to gather specifics about the installation site. Our analysts also perform a comprehensive energy audit that ascertains your current energy consumption and power requirements, and will advise on best practice and energy efficient solutions in order to optimise your power consumption.

Step 2 : Site Assessment and Lightning Risk Assessment

The site layout and construction can have a large impact on the performance of any system, transitioning from traditional fossil fuel sources to renewable energy source.  EEC utilises its vast industry specific knowledge to analyse all the physical aspects of the site from what the ideal location of the PV panels would be up to the perfect locations for battery storage and other sensitive equipment to ensure optimal performance as well as longevity. The site inspection is also critical in identifying the most cost-effective energy solution. We can also conduct a detailed lighting risk assessment and provide lighting protection design. 

Step 3: Systems Design and Energy Development Plan

Our team of qualified engineers select the correct components from quality local and international brands with exceptional performance and matching warranties, to populate the system. Various configurations are considered to ensure that we arrive at a system that will guarantee performance for up to 25-years and beyond. For most clients, a primary motivator for investing in solar is to realise financial savings as well as achieve great returns on their investments; however, savings can only be realised with a system that has been designed correctly and continues to deliver well into – and even beyond – its 25 year life.

Step 4 : Energy System Installation

Any system can utilise the best possible equipment and be design to achieve the greatest efficiency however all of this can potentially be for nothing if the system is not correctly and effectively installed. EEC has a vast network of electricians and skilled installers that perform the installation of the system under the expert eye of an experienced and qualified engineer.

Step 5: Energy Systems  Benchmarking and Commissioning

We take great care and pride to ensure each and every step in delivering an efficient and effective system, from the energy audit through to the commissioning, is done correctly and professionally. The commissioning of a system is done in order to ensure the system is performing as per the agreed upon requirements and to benchmark with respect to the design. In so doing the client is secure in the knowledge that the system has been designed and installed by a qualified, reputable company and the commissioning certificate is more than simply a piece of paper – it is peace of mind

Step 6 : Systems Monitoring and Maintenance 

Information is power, and with this in mind we facilitate a user-friendly reporting system, providing empirical data that depicts vital statistic such as savings, environmental benefits, faults etc. These are compared to predefined base lines to ensure that your system is performing optimally and providing you with the expected return. 


The sustainable development of your business’s energy systems, benefits both your bottom line and contributes to the environmental sustainability goals of the country. Take the first steps towards a sustainable future. With these clean energy solutions you can tell your investors, not only are you cutting the power bill, but you are promoting your brand images as ‘combating climate change’ and generating positive media. It’s all about perspective!
