Bioenergy
Bioenergy is a type of renewable energy that is derived from plants and animal waste.[1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants.[2] Thus, fossil fuels are not regarded as biomass under this definition. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms.[3]
Bioenergy can help with climate change mitigation but in some cases the required biomass production can increase greenhouse gas emissions or lead to local biodiversity loss. The environmental impacts of biomass production can be problematic, depending on how the biomass is produced and harvested.
The IEA's Net Zero by 2050 scenario calls for traditional bioenergy to be phased out by 2030, with modern bioenergy's share increasing from 6.6% in 2020 to 13.1% in 2030 and 18.7% in 2050.[4] Bioenergy has a significant climate change mitigation potential if implemented correctly.[5]: 637 Most of the recommended pathways to limit global warming include substantial contributions from bioenergy in 2050 (average at 200 EJ).[6]: B 7.4
Plymouth (/ˈplɪməθ/ ⓘ PLI-məth) is a port city and unitary authority in Devon, South West England. It is located on Devon's south coast between the rivers Plym and Tamar, about 36 miles (58 km) southwest of Exeter and 193 miles (311 km) southwest of London. It is the most populous city south of London.
Plymouth's history extends back to the Bronze Age, evolving from a trading post at Mount Batten into the thriving market town of Sutton, which was formally re-named as Plymouth in 1439 when it was made a borough. The settlement has played a significant role in English history, notably in 1588 when an English fleet based here defeated the Spanish Armada, and in 1620 as the departure point for the Pilgrim Fathers to the New World. During the English Civil War, the town was held by the Parliamentarians and was besieged between 1642 and 1646. In 1690 a dockyard was established on the River Tamar for the Royal Navy and Plymouth grew as a commercial shipping port throughout the Industrial Revolution.
After absorbing nearby settlements in 1914, the borough was awarded city status in 1928. During World War II, Plymouth suffered extensive damage in the Plymouth Blitz, leading to post-war rebuilding that significantly shaped its modern appearance. A further expansion of its boundaries in 1967 contributed to its current status as the 30th-most populous built-up area in the UK and the second-largest city in the South West after Bristol, with a population in 2021 of 264,727.
Plymouth's economy, historically rooted in shipbuilding and seafaring, has transitioned towards a service-based economy since the 1990s. It maintains strong maritime connections, hosting HMNB Devonport, the largest operational naval base in Western Europe, and offering ferry links to Brittany and Spain. The city is also home to the University of Plymouth, reflecting its educational and cultural significance. Today, the city is governed locally by Plymouth City Council and is represented nationally by two Members of Parliament.
