Renewable Energy
Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can move heat and vehicles efficiently and is clean at the point of consumption.[1][2] Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power.
Renewable energy systems have rapidly become more efficient and cheaper over the past 30 years.[3] A large majority of worldwide newly installed electricity capacity is now renewable.[4] Renewable energy sources, such as solar and wind power, have seen significant cost reductions over the past decade, making them more competitive with traditional fossil fuels.[5] In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity.[6] From 2011 to 2021, renewable energy grew from 20% to 28% of global electricity supply. Power from the sun and wind accounted for most of this increase, growing from a combined 2% to 10%. Use of fossil energy shrank from 68% to 62%.[7] In 2022, renewables accounted for 30% of global electricity generation and are projected to reach over 42% by 2028.[8][9] Many countries already have renewables contributing more than 20% of their total energy supply, with some generating over half or even all their electricity from renewable sources.[10][11]
The main motivation to replace fossil fuels with renewable energy sources is to slow and eventually stop climate change, which is widely agreed to be caused mostly by greenhouse gas emissions. In general, renewable energy sources cause much lower emissions than fossil fuels.[12] The International Energy Agency estimates that to achieve net zero emissions by 2050, 90% of global electricity generation will need to be produced from renewable sources.[13] Renewables also cause much less air pollution than fossil fuels, improving public health, and are less noisy.[12]
The deployment of renewable energy still faces obstacles, especially fossil fuel subsidies,[14] lobbying by incumbent power providers,[15] and local opposition to the use of land for renewable installations.[16][17] Like all mining, the extraction of minerals required for many renewable energy technologies also results in environmental damage.[18] In addition, although most renewable energy sources are sustainable, some are not.
Birmingham (/ˈbɜːrmɪŋəm/ (About this soundlisten)[3][4] BUR-ming-əm) is a city and metropolitan borough in the West Midlands, England. It is the second-largest city, urban area and metropolitan area in England and the United Kingdom,[b] with roughly 1.1 million inhabitants within the city area, 2.9 million inhabitants within the urban area and 4.3 million inhabitants within the metropolitan area and lies within the most populated English district.[5][6][7][8][9][10][10][11] Birmingham is commonly referred to as the second city of the United Kingdom.[12][13]
Located in the West Midlands county and region in England, approximately 100 miles (160 km) from Central London, Birmingham, as one of the United Kingdom's major cities, is considered to be the social, cultural, financial, and commercial centre of both the East and West Midlands. Distinctively, Birmingham only has small rivers flowing through it, mainly the River Tame and its tributaries River Rea and River Cole – one of the closest main rivers is the Severn, approximately 20 miles (32 km) west of the city centre.
A market town of Warwickshire in the medieval period, Birmingham grew in the 18th-century Midlands Enlightenment and subsequent Industrial Revolution, which saw advances in science, technology, and economic development, producing a series of innovations that laid many of the foundations of modern industrial society.[14] By 1791, it was being hailed as "the first manufacturing town in the world".[15] Birmingham's distinctive economic profile, with thousands of small workshops practising a wide variety of specialised and highly skilled trades, encouraged exceptional levels of creativity and innovation and provided an economic base for prosperity that was to last into the final quarter of the 20th century. The Watt steam engine was invented in Birmingham.[16]
The resulting high level of social mobility also fostered a culture of political radicalism which, under leaders from Thomas Attwood to Joseph Chamberlain, was to give it a political influence unparalleled in Britain outside London, and a pivotal role in the development of British democracy.[17] From the summer of 1940 to the spring of 1943, Birmingham was bombed heavily by the German Luftwaffe in what is known as the Birmingham Blitz. The damage done to the city's infrastructure, in addition to a deliberate policy of demolition and new building by planners, led to extensive urban regeneration in subsequent decades.
Birmingham's economy is now dominated by the service sector.[18] The city is a major international commercial centre and an important transport, retail, events and conference hub. Its metropolitan economy is the second largest in the United Kingdom with a GDP of $121.1bn (2014),[2] and its six universities make it the largest centre of higher education in the country outside London.[19] Birmingham's major cultural institutions – the City of Birmingham Symphony Orchestra, the Birmingham Royal Ballet, the Birmingham Repertory Theatre, the Library of Birmingham and the Barber Institute of Fine Arts – enjoy international reputations,[20] and the city has vibrant and influential grassroots art, music, literary and culinary scenes.[21] The city will host the 2022 Commonwealth Games.[22] Birmingham is the fourth-most visited city in the UK by foreign visitors.[23]
