The European Marine Energy Centre (EMEC) Ltd. is a UKAS accredited test and research centre focused on wave and tidal power development, based in the Orkney Islands, UK. The centre provides developers with the opportunity to test full-scale grid-connected prototype devices in wave and tidal conditions, at pre-consented test sites. EMEC also has sites for testing smaller-scale prototypes in more sheltered conditions.
China is the world leader in wind power generation, with the largest installed capacity of any nation and continued rapid growth in new wind facilities. With its large land mass and long coastline, China has exceptional wind power resources: Wind power remained China's third-largest source of electricity at the end of 2021, accounting for 7.5% of total power generation.
GE Power was an American energy technology company owned by General Electric (GE). In April 2024, GE completed the spin-off of GE Power into a separate company, GE Vernova. Following this, General Electric ceased to exist as a conglomerate and pivoted to aviation, rebranding as GE Aerospace.
The electricity sector in Sri Lanka has a national grid which is primarily powered by hydroelectric power and thermal power, with sources such as photovoltaics and wind power in early stages of deployment. Although potential sites are being identified, other power sources such as geothermal, nuclear, solar thermal and wave power are not used in the power generation process for the national grid.
GE Offshore Wind is a joint venture with Alstom and a subsidiary of GE Vernova, created in 2015 when most of Alstom's electrical power and generation assets were acquired by General Electric. GE's stake in the joint venture is 50% plus 1 share.

As of 2018, hydroelectric power stations in the United Kingdom accounted for 1.87 GW of installed electrical generating capacity, being 2.2% of the UK's total generating capacity and 4.2% of UK's renewable energy generating capacity. This includes four conventional hydroelectric power stations and run-of-river schemes for which annual electricity production is approximately 5,000 GWh, being about 1.3% of the UK's total electricity production. There are also four pumped-storage hydroelectric power stations providing a further 2.8 GW of installed electrical generating capacity, and contributing up to 4,075 GWh of peak demand electricity annually.
GE Digital is a subsidiary of American energy conglomerate GE Vernova. Headquartered in San Ramon, California, the company provides software and industrial internet of things (IIoT) services to industrial companies.
The Nachtigal Hydroelectric Power Station is a 420 megawatt run-of-the-river hydroelectric power station under development in Cameroon across the Sanaga River, which harnesses the energy of the Nachtigal Falls. The development rights were granted to Nachtigal Hydro Power Company (NHPC), a company owned by a consortium comprising (a) Électricité de France (b) International Finance Corporation and (c) the Government of Cameroon. A 35-year power purchase agreement is in place, between Eneo Cameroon S.A. and NHPC.
Many tidal stream generators have been developed over the years to harness the power of tidal currents flowing around coastlines. These are also called tidal stream turbines (TST), tidal energy converters (TEC), or marine hydro-kinetic (MHK) generation. These turbines operate on a similar principle to wind turbines, but are designed to work in a fluid approximately 800 times more dense than air which is moving at a slower velocity. Note that tidal barrages or lagoons operate on a different principle, generating power by impounding the rising and falling tide.
GE Vernova Inc., formerly GE Power and GE Renewable Energy, is an energy equipment manufacturing and services company headquartered in Cambridge, Massachusetts.
