Renewable Energy in Dutch Caribbean
There are various green community projects in the Caribbean aimed at promoting sustainability, environmental conservation, and community development. Here are some general aspects and examples which should be considered and supported to creating a brighter and greener tomorrow for many of us.
Renewable Energy Initiatives
Many Caribbean islands face energy challenges, and several community projects focus on adopting renewable energy sources such as solar and wind power. Some projects involve installing solar panels on community buildings, promoting energy efficiency, and educating locals about sustainable energy practices.
At the 5th annual German-Caribbean Energy Conference in Aruba organized by the Dutch German Chamber of Commerce [https://www.dnhk.org] renewable supply-dependent potentials studies were presented by:
Our volunteer colleague Mr. Dirk Bonse of the German Biogas Association. Mr. Bonse presented technological options for Biomethane Production from Raw Biogas to Biomethane. Mr. Bonse presented small-scale Biogas or Biomethane solutions for households that involve the conversion of organic waste into methane gas for cooking, heating/cooling, or other energy needs. These systems can be particularly beneficial in rural or off-grid areas where access to traditional energy sources may be limited.
Explained were subjects such as Biogas Production which can be derived from various organic materials, such as kitchen waste, agricultural residues, animal manure, and sewage. A common method for small-scale Biogas production is anaerobic digestion. Microorganisms break down organic matter in the absence of oxygen, producing Biogas as a byproduct which in turn can supply appliances for cooking, heating and cooling. Biodigester types, installation and simplified maintenance were explained.
Appealing benefits are that Biogas is a renewable energy source that reduces reliance on traditional fuels. It helps in managing organic waste, contributing to waste reduction and environmental sustainability (waste management). And Biogas production can lead to cost savings on cooking and heating expenses (cost savings).
Challenges are successful implementation may require technical knowledge and expertise. However locals can be taught how to install, maintain and or expand systems for Biogas / Biomethane production. There may be upfront costs (Initial Investment) for installing the system, although the long-term benefits often outweigh these costs.
The success of such projects is often linked to community participation and acceptance. Here is where Stichting Marlin Yard comes in with regards to Community Engagement. We believe that Small-scale Biogas solutions can contribute to sustainable development by providing clean energy and addressing waste management challenges at the local level. This is why Stichting Marlin Yard has incorporated small scale Biogas solutions in its Green Community projects designed for Aruba and Sint Maarten. The Green Community projects are listed on www.caribhousing.com. We are also open to assisting interested parties in creating more Green Communities throughout the Caribbean.
Also dr. Matthias Stark, Head of renewable energy systems of the German Renewable Energy Federation also known as the BEE – Bundesverband Erneurbare Energie e.V confirmed potentials for the specific islands Aruba, Curacao and Bonaire compared to studies regarding the country Germany.
Regarding Wind energy all three islands have extremely high and, above all, consistent wind potential. The average annual wind speed is over 10 m/s compared to Germany comparison which has approx. 6 m/s. As for Solar energy, all three islands have an excellent solar supply with annual yields of approx. 1,700 h/a, compared to Germany comparison: ca. 1.000 h/a.
Here are a few results:
Aruba: Calculation of wind energy feed-in was based on hourly wind speeds between 2010 to 2020. The power curve of the V90 (existing wind farm Vader Piet on Aruba https://www.windbase.eu/projects/wind-farm-vader-piet-aruba.aspx) was used to calculate the feed-in. Aruba annual electricity consumption is ca. 1.100 GWh. Studies showed that a climate-neutral path for Aruba is possible when combining wind energy, photovoltaics, deployment of storage capacity, storage power and gas turbine capacity (bio or green hydrogen) to reach the target coverage of >99.9% residual demand.
Results for Curacao with an annual electricity consumption ca. 1.000 GWh – are similar to Aruba due to very similar framework conditions (weather, load profile). However a stronger focus on wind energy compared to photovoltaics can be seen. A climate-neutral path can also be realized in Curacao.
Results Bonaire with an annual electricity consumption ca. 170 GWh – are similar to Aruba due to very similar conditions (weather, load profile). The specific installations are lower due to the lower consumption. A climate-neutral path can also be realized in Bonaire.
With the knowledge and received recipe on how Aruba, Curacao and Bonaire can become climate neutral, we are joining this mission to make this happen. Let’s start with getting more windfarms connected indefinitely to the power grid and take it from there…
We make it our business to promote sustainability when it comes to community development. We believe in creating a brighter, greener tomorrow and getting communities engaged to be part of a unique opportunity. Invest in sustainable initiatives that promise not only financial returns but a positive impact on our planet. We envision a world where sustainability and profitability coexist harmoniously. Our Eco Shares Program is designed to empower you to contribute to environmental solutions while enjoying the rewards of green investments.
