Projects mostly consist of solar-plus-storage microgrids in rural areas with sufficient population density. The main driver for solar-powered microgrids is their cost-effectiveness relative to fuel-powered microgrids, a grid extension, kerosene lamps, or diesel generators. Renewable microgrids are also generally more reliable than the grids in developing countries.
The advantage of community energy over other electrification models is strong community buy-in and empowerment. The same rationale applies to many island markets and remote areas in developed countries. On the flipside, some communities in developed countries are pursuing community renewable energy as a means to go off grid. This is notably the case in Australia, where community energy grew strongly in In areas with developed electric grids, community energy provides shared ownership or access to wind and solar resources.
Energy cooperatives are the most common structures and involve shared citizen ownership and operation of renewable resources. Germany is the global energy cooperative leader: Over two-fifths of renewable energy installed in the country last year was cooperative-owned, and Germany recently implemented new rules to level the playing field for energy cooperatives to participate in power auctions.
Almost half of US households and businesses cannot host a solar system for lack of suitable or accessible roof space; community energy enables them to buy electricity from a shared solar project and receive a credit on their utility bill. Third-party providers administer two-thirds of community solar capacity, primarily to commercial customers and mostly in Colorado, Minnesota, and Massachusetts, with utilities accounting for the rest and primarily serving residential customers.
This is the case in Japan, which has a national resilience plan supportive of community energy. While cities and communities are increasingly relevant actors in the deployment of solar and wind power in developed markets, the national level is most relevant in emerging markets. The solar and wind industries and markets started and matured in the developed world defined as the 33 high-income OECD members , but their center of gravity has shifted to emerging markets all nondeveloped countries.
In , emerging markets surpassed the developed world in onshore wind growth, and in , solar PV growth; in , they accounted for 63 percent of global new investment in renewable energy, widening the investment gap with developed countries to a record high. Emerging markets have helped bring down the cost of renewables, allowing them to leapfrog developed countries in the deployment of renewables, pursue less carbon-intensive development, and innovate in ways that also benefit the developed world.
As the global leader, China is propelling the ascent of emerging markets in renewable energy growth. China recorded the largest solar and wind growth and total installed capacities in and is the only market above GW for both sources.
China alone accounted for over half of new solar capacity installations as well as two-thirds of global solar PV panel production in Eight of the top ten solar PV suppliers are Chinese, and the top three Chinese wind companies together account for the largest wind market share. Even without China, emerging markets are driving renewable energy growth and have the greatest potential to drive future growth. For the most marginalized unelectrified populations in low-density areas, pay-as-you-go solar home systems are often the best electrification option.
The International Energy Agency estimates that in the next two decades, most people without electricity will gain access through decentralized solar PV systems and microgrids. Emerging markets are incubating innovation. Developed countries have benefitted from market and product designs that initially took off in emerging countries. For example, renewable energy auctions are a trend that emerging markets embraced first and that has brought steep declines in renewable prices across the globe.
OED: Renewable Energy Sources
For example, microgrids designed to electrify off-grid areas in developing countries have found applications in remote mines in developed countries. More broadly, corporations play a growing role in facilitating transfers between developed and developing countries that promote renewable energy growth. Corporations are procuring renewable energy in new ways, with a growing number of industry sectors involved. Power purchase agreements PPAs are becoming the preferred tool as corporations become increasingly concerned about the quality of their procurement: The gold standard is additionality, that is, assurance that the procurement creates measurable, additional renewables capacity.
PPAs provide the greatest additionality, but are primarily accessible to large corporations. Aggregation is starting to expand access to smaller players. The largest corporations are also requiring and helping smaller companies to procure renewables as they have encompassed supply chains in their renewable targets. PPAs are the most rapidly growing corporate procurement tool. Corporations sourced terawatt hours TWh of renewables globally in through self-generation or procurement.
EACs, the most widely used procurement tool, are available in 57 countries and are easy to procure. They allow companies to certify compliance with government renewable requirements or voluntary targets. However, they do not capture the full cost benefit of renewables and may not always provide additionality. UGPs are available in 39 countries, mostly in Europe, but are the least used and least transparent tool. They are often tied to EACs and share the same drawbacks. PPAs are available in 35 countries and rapidly spreading. In , corporations signed a record 5.

However, they are more difficult for smaller players to access. They are a preferred tool for companies with electricity costs exceeding 15 percent of operational expenditures. All three tools are available in North America and most European countries. These developed countries continue to be the leading corporate procurement markets, and information technology remains the leading sector.
However, companies in other sectors are increasing renewable procurement as well, and emerging markets are making it easier. Emerging markets India and Mexico also offer a full toolkit and are seeing growing multinational and national corporate procurement. A corporate compound effect can be achieved through aggregation and supply chains. Two-thirds of Fortune companies have set renewable energy targets and are leading global corporate procurement through PPAs. Many of them have joined RE, a group of companies as of September that have committed to sourcing percent of their electricity from renewables.
Through aggregation, smaller players can form partnerships to jointly execute a utility-scale PPA. Some project developers are now meeting these smaller companies halfway by aggregating a series of PPAs.
