Pay-as-you-go (PAYG) is an innovative business model where energy service companies sell or lease solar photovoltaic (PV) systems, usually solar home systems (SHS), to customers in exchange for regular payments via mobile money, cash or scratch cards [1]. Due to the range of packages available, customers can choose from starter kits that supply a few lights and charge cell phones, to larger systems that can power TVs, radios, stoves and small fridges [1][2]. In some cases, if a customer cannot make payments, the energy service provider is able to switch off the system remotely, and switch them on again once payment is made [2
Green hydrogen refers to hydrogen gas produced through a process called electrolysis, using renewable energy sources such as wind, solar, or hydroelectric power. It’s called “green”” because the energy used in its production comes from sustainable and clean sources, resulting in minimal or no greenhouse gas emissions. The process of creating green hydrogen involves splitting water molecules (H2O) into hydrogen (H2) and oxygen (O2) through electrolysis. During electrolysis, an electric current passes through water, causing the water molecules to dissociate into their constituent elements: hydrogen and oxygen. The hydrogen produced in this way can be stored and used as a clean energy carrier in various sectors, such as transportation, industry, and power generation.”
Energy storage refers to technologies that capture one form of energy (usually electrical) when generated and store it as another (chemical, thermal, mechanical or electrochemical) for release when required [1]. Storage is essential for enabling the use of variable renewable energy (vRE) such as solar and wind due to its intermittent nature.
Crowdfunding is where several individuals contribute small sums of money in order to fund a project. Given the low risk that each person takes on, crowdfunding can be an innovative financing tool, including for local renewable energy (RE) projects [1]. They can also help involve the local community in various ways, increasing buy-in and ensuring the long-term sustainability of the project [2]. This solution addresses the use of crowdfunding for the local energy transition, and how local and regional governments (LRGs) can take advantage of it while protecting the best interests of their communities.
Multilevel governance is an approach to governance from the national to local level which provides a platform for fruitful interaction, joint planning and coordination, all of which are essential to the mutual reinforcement of approaches for addressing climate change, sustainable development, implementation and reporting.
