Renewable Energy in the Caribbean
For years, nations around the world have derived electricity from centralized energy grids. These grids often originate from powerful political hubs such as the USA or the Middle East and incur substantial transportation costs due to the large geographic areas which they serve. These centralized grids are a product of industrial-era fossil fuel energy, harvested at specific locations such as coal mines or oil fields. The high delivery costs incurred by centralized grids create systemic fragility, especially when faced with natural disasters that can force the shutdown of large swaths of energy grids and prevent the delivery of resources.

The multiple island nations populating the Caribbean have depended on these imported energy sources for decades, often leading to high energy transportation costs and long blackout periods during natural disasters. Thus, the Caribbean has become a critical region for developing sustainable microgrids that generate and disseminate localized electricity harvested from abundant renewable resources such as sunlight and wind. Microgrids allow regions to be self-sufficient when it comes to electricity consumption and thus gain increased resilience when it comes to recovering from disasters such as hurricanes, making renewable energy in the Caribbean an attractive option.

The Rocky Mountain Institute

One significant company operating within the Caribbean is the Rocky Mountain Institute. The institute is a U.S.-based organization focused on sustainability research and aid. The company has many partnerships and projects in progress in the Caribbean, including building multiple solar panel arrays, microgrids generators and wind turbines throughout the islands.

The Rocky Mountain Institute primarily advises governments and utility providers on how to best build and maintain sustainable energy infrastructure. Throughout the Caribbean islands, the institute oversees projects ranging from microgrid development and electricity storage to sustainable streetlights and floating solar arrays.

Economic Impact

The shift to sustainable energy and decentralized microgrid architecture presents not only an environmental opportunity but an economic one as well. The rapid expansion of renewable infrastructure in the Caribbean can add a projected 1,750 jobs to the economy over five years by focusing on building solar and wind energy generators and refitting traditional cars into electric cars. The Rocky Mountain Institute is also projecting 80% energy cost savings with the implementation of energy-efficient updates to current buildings.

The introduction of sustainable energy can also lower electricity prices significantly within this region. The Caribbean Development Bank and the Inter-American Development Bank have given $71.5 million in grants, distributed by the Sustainable Energy Facility, to eastern Caribbean countries in order to expand the geothermal infrastructure within the islands. Eastern Caribbean countries currently have an average electricity price of $0.34 per kilowatt-hour (for those using 100 kWh or less per month) with the highest prices existing in Grenada at $0.42 and the cheapest prices seen in St. Lucia at $0.34 per month.

Conclusion

The introduction of renewable energy in the Caribbean is increasing competition in regional electricity markets and driving down prices. The regional investments in renewable energy in the Caribbean, driven by the organizations described above, act to stimulate job creation and increase economic independence by generating energy cost savings, expanding local energy production and developing greater resilience to natural disasters by way of sustainable microgrids. With further adoption of this technology, the Caribbean could continue its strides toward sustainability.

Solving Energy Poverty
Access to electricity and other forms of energy is so ubiquitous in the United States and other developed economies, that it is easy to forget that energy poverty persists in the developing world. Yet, energy poverty (the lack of access to modern energy services including electricity and clean cooking facilities) remains a barrier to global prosperity and individual well-being. At the current rate of progress toward the United Nations’ goal of universal energy access, 650 million people will still be in the dark in 2030. However, people can solve the problem of energy poverty in developing nations. Moreover, they can tackle energy poverty without a significant contribution to global greenhouse gas emissions. Here are three sustainable technologies solving energy poverty.

3 Sustainable Technologies Solving Energy Poverty

  1. Microgrids: Microgrids are small, localized power grids that operate on renewable energy, diesel back-up and batteries. With low costs and high yields, microgrids are an affordable and sustainable solution to energy poverty. The price of batteries, solar and other energy technologies has been decreasing since 2010, reducing the cost of operation. According to the International Energy Agency, microgrids are the most cost-effective option to deliver electricity to more than 70 percent of the unconnected. By powering fridges, fans, irrigation pumps and other machinery, microgrids have saved time for families on household chores, helped farmers increase crop yield and light classrooms. In India, a project that Smart Power India and the Rockefeller Foundation launched is using microgrids to power more than 100 villages serving 40,000 people. More than 140 microgrids that this initiative has built have helped to alleviate energy poverty in the region.
  2. Biogas Digesters: Biogas digesters burn organic waste to generate odorless, clean-burning methane. Some experts consider them carbon-neutral because they offset more emissions than they create. The average home biogas system can reduce firewood use by up to 4.5 tons each year, which translates into four tons of greenhouse gas emissions. Biogas digesters are a sustainable, reliable technology for powering gas stoves and lights, requiring little maintenance and is safer than combustible tanks of liquid petroleum gas. Because of their potential to alleviate energy poverty, the government of Nepal, through its Alternative Energy Promotion Center, has helped build more than 200,000 biogas systems across the country and aims to increase that number to two million.
  3. LED Lighting: Solar-powered LED lights are delivering electricity to those unable to plug into power grids. Thanks to extensive innovation in the field, people can now also use many LED lights to power phone charging and small fans. LED has a long service life, between 10 and 20 years, which makes it a reliable form of sustainable lighting. They are also portable, easy to install and safer than fuel-based lighting. People unable to connect to an electric grid have bought more than 2.1 million LED-solar products globally. According to the IFC-World Bank Lighting Africa program, nearly 5 percent of Africans without access to electricity, around 28.5 million people, currently use LED lighting. Nonprofit organizations, such as Solar Aid, are increasing that number as well by introducing solar LED lights to other economically poor areas to sustainably combat energy poverty.

Limited access to reliable, modern and affordable energy services hinders communities and cripples economies. That is why achieving the United Nations’ Sustainable Development Goal of universal energy access by 2030 is so critical. These three sustainable technologies solving energy poverty are leading the way.
