“…The energy demand by sectors breaks down to 41 % electricity generation, 27 % transportation, 10 % commercial and public, 9 % industry, 9 % residential and 5 % other (IRENA, 2016). The retail energy price in Barbados, which can rank among the highest in the Caribbean, varies significantly with the price of international oil and is allocated to energy consumers through the Fuel Clause Adjustment (GOB, 2019;Henry et al, 2015).…”

“…With a dependence of more than 95 % on fossil fuel imports, Barbados faces economic vulnerabilities that translate into high electricity prices (Henderson, 2013). At the same time, Barbados is the first island in the English-speaking Caribbean to commit to using 100 % renewable energy (Henry et al, 2015). The heavy reliance on fuel imports for energy generation and transportation has affected and is affecting the nation's economic growth and social development.…”

The high dependence on imported fuels and the potential for both climate change mitigation and economic diversification make Barbados' energy system particularly interesting for detailed transformation analysis. An open source energy system model is presented here for the analysis of a future Barbadian energy system. The model was applied in a scenario analysis to investigate cost-optimal and 100% renewable energy system configurations. Within the scenarios, the electrification of private passenger vehicles and cruise ships through shore-to-ship power supply was modelled to assess its impact on the energy system and the necessary investment in storage. Results show that for most scenarios of a system in 2030, a renewable energy share of over 80% is achieved in cost-optimal cases, even with a growing demand. The system's levelised costs of electricity range from 0.17 to 0.36 BBD/kWh in the cost-optimal scenarios and increase only moderately for 100 % renewable systems. Under the reasonable assumption of decreasing photovoltaic investment costs, system costs of a 100 % system may be lower than the current costs. The results show that pumped hydro-storage is a no-regret option for the Barbadian power system design. Overall, the results highlight the great economic potential of renewable

“…"The other [way] is to generate electricity by substituting the traditional use of fossil fuels with renewable sources" [32]. "Wind energy is the preferred technology for power generation for supply to the national grid" [33] but [34,35] have even been exploring the possibility of wave energy for SIDS. By incorporating these forms of renewable energy (RE) into the energy mix, Trinidad and Tobago is poised to further reduce the cost of producing electricity.…”

The transport sector has been identified as one of the highest contributors to greenhouse gas emissions in Trinidad and Tobago owing to the increase in the number of vehicles and the inherent traffic congestion. The vehicles are mainly fuelled by conventional fuels with relatively few being alternative fuel vehicles (AFVs), primarily in the form of compressed natural gas (CNG) vehicles. This research explores the current situation with the development and adoption of AFV technology in Trinidad & Tobago. In Trinidad, the natural gas supply is already well-established, refuelling stations are in operation and up to 18 original equipment manufacturer CNG vehicles are available on the market, supplemented by the option of vehicle conversion. The opposite is true for electric vehicles, with only one recognized dealer offering electric vehicles and public charging stations, and only one related market incentive in effect. Despite the number of initiatives geared toward CNG development, the 2018 vehicle conversion targets have not been realized and it would require a very aggressive approach to achieve those figures by 2020. The authors have identified the key impediments to successful attainment of the targets. They note that few of the ongoing fiscal incentives, measures or pilot projects by the government ministries that are associated with renewable energies are directly linked to the transportation sector. Additionally, since measures of effectiveness for sustainability are not being monitored, the country cannot adequately determine its progress towards sustainability. The authors propose measures towards achieving sustainable development in transportation and to overcome the constraints of data availability, perceived barriers to AFV adoption and the notion of affordability over sustainability.
