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.
Ipswich (/ˈɪpswɪtʃ/ (About this soundlisten)) is a historic county town in Suffolk, England. The town is located in East Anglia about 10 miles away from the mouth of the River Orwell and the North Sea. Ipswich is both on the Great Eastern Main Line railway and the A12 road, it is 66 miles (106 km) north-east of London, 54 miles (89 km) east-southeast of Cambridge, and 45 miles (72 km) south of Norwich. Ipswich is surrounded by two Areas of Outstanding Natural Beauty (AONB); Suffolk Coast and Heaths and Dedham Vale.
Ipswich's modern name is derived from the medieval name Gippeswic, likely taken either from an Old Saxon personal name or from an earlier name given to the Orwell Estuary (although unrelated to the name of the River Gipping).[1][2] It has also been known as Gyppewicus and Yppswyche.[3] The town has been continuously occupied since the Saxon period,[3] and is contested to be one of the oldest towns in the United Kingdom.[4] Ipswich was a settlement of great economic importance to England throughout its history, particularly in trade.[5] The town's historical dock, present-day Ipswich Waterfront, was known as the largest and most important dock in the kingdom.[5][6]
Ipswich is a non-metropolitan district and is a large settlement despite its town status. The urban development of Ipswich overspills the borough boundaries significantly, with 75% of the town's population living within the borough at the time of the 2011 Census, when it was the fourth-largest urban area in the United Kingdom's East of England region, and the 42nd-largest urban area in England and Wales.[7] In 2011, the town of Ipswich was found to have a population of 133,384,[8][9] while the Ipswich built-up area is estimated to have a population of approximately 180,000 in 2011.[7]
The town is split into various quarters, with central and the waterfront drawing the most footfall.[10] Central is home to the town's retail shopping and the historical town square, the Cornhill. The waterfront is located south of the town centre on the bend of the River Orwell and is a picturesque setting housing the town's impressive marina. The waterfront was historically an industrial port but has since been transformed into a trendy area lined with high-rise apartment buildings, restaurants, bars and cafés. The waterfront is also home to one of the UK's newest universities, the University of Suffolk, which was formed in 2016.[11]
Ipswich has become a tourist hotspot in the UK with 3.5 million people reported to have visited the county town in 2016.[12] In 2020, Ipswich was ranked as an emerging global tourist destination by TripAdvisor.[13] Ipswich was voted as the 7th most desirable place to live and work in England by the Royal Mail in 2017.[14] In 2007, Ipswich was awarded the cleanest town award,[15] and in 2015, Ipswich was rated as the third happiest place to live in the UK.[16]
