Who is leading in renewable energy? | CNBC Explains

All various regions of the world, authorities are building more solar parks, gale farms and hydroelectricpower plants to generate power. As global warming and climate changecontinue to take centre stage, which countries are conducting in generatingpower through renewable energy? And what are the challengespreventing mass adoption? In 2018, more than a one-quarter of the worldsenergy was generated from renewable sources, thanks to costs coming down andmore light-green programs taking off. Renewable energy cancome from many informants. The most common are solar, gale, geothermal, biomass and hydropower. In sunny Singapore, solar powerwould seem like the natural fit. So whats preventingits mass ratification? Well, its not thatstraightforward. For one, the unpredictable cloudcover over the minuscule city-state. And not all countries have the samepotential to harness empty intensity or the right environment forcertain energy infrastructure. Let’s take a look at whosleading the intensity revolution.China, the United Government, Brazil, Indiaand Germany have the biggest renewable superpower capacity worldwide, in no tiny fraction due to their size. Remove hydropower from the mixture andGermany moves up to number three and Japan makes thenumber five blot. But its no coincidence that these six countries alsomake the schedule of the worlds biggest vigor purchasers, meaning that even if they were producingrenewable energy at faculty, it still compiles up a small proportionof their overall vigor desegregate. Divide renewable dominance ability by thenumber of people living in the country, and you get a verydifferent mix of countries.Iceland is the world leader, followed by Denmark. Germany and Sweden aretied in the third spot. And Finland roundsout the top five. But the most telling metric is likely the role ofrenewables in a countrys overall vitality mixture. Nordic and Latin American countrieshave a good present on such lists. More than 75% of Norway, New Zealand, Brazil andColombias energy production comes from renewables. Venezuela, Canada, Sweden andPortugal too make a good presentation. But for large-hearted lubricant developing commonwealths like SaudiArabia, Kuwait, the U.A.E and Algeria, renewables are unsurprisinglynear non-existent. But again , not all countries haveequal geographies and policies. Think of renewable energy as something bespoke, with each country exploiting the environment according to itsunique encloses. Norway has 1,660 hydropower plants andmore than 1,000 storage pools. It is possible for Norway to depend on hydropowerbecause of the countrys long coastlines, steep valleys and highlevels of running water. In neighbouring Sweden, where forestsmake up 63% of its land mass, bioenergy is increasingly being used forheating, as well as for electricity production. 11% of its energy is also derivedfrom around 3,600 air turbines.Likewise in Brazil, which has rivers and vast swathesof the Amazon rainforest within its borders. Clean energy, including hydropower, accountedfor 42% of its electricity generation in 2017. Ditto for Colombia and Venezuela, countries known for hydroelectricity. One notorious cautionary falsehoods about over-reliance onone form of renewable energy comes from Venezuela, which depends heavily on the Guri dam forabout 60% of the countrys electrical needs. In 2010 and 2016, droughts compelled the barriers ocean tofall so low, the government had to declare disasters. So where does the energyrace continue from here? Well, an increasing number of countriesare recognizing the urgent need to tackle, or slow downclimate change. Investing in renewable energyis one of the major steps. From the Kyoto Protocol to the Paris Agreement, an increasing number of signatories are joining international environmental agreementsto lower radiations of greenhouse gases.The Paris Agreement brought together 195 nations to tackle climate change in 2015, though it has had afew setbacks since. The United States will withdraw from the ParisClimate Accord. So were going out. But we will start to negotiate, and we willsee if we can make a deal thats fair. Other targets include the UN SustainableDevelopment Goal for Affordable and Clean Energy, which includes increasing the share of renewableenergy in the world vitality concoction by 2030. In the meantime, countries haveset unilateral targets as well. More than 60 countries are planning to bringtheir carbon footprint to zero by 2050, with the European Union aiming tobecome the first environment neutral economy. But most renewable energy sources are stillsubject to irregular powers of nature. Imagine a drought rendering a dam uselessand taking out a countrys sole electricity supply. Or occasional vigor from windor solar generators. What then? Thats where innovation andnew technologies kick in. Remember when billionaire Elon Musk tweetedthat he would invest a battery storage system in South Australia within1 00 dates, or deliver it for free? The Tesla battery system now impounds the titlefor the largest lithium-ion battery in the world.It can currently collect 129 megawatt-hours of energy from gust turbines by renewablepower company Neoen. This is enough to meet theneeds of 30,000 residences. Now, Neoen has plans to upgrade itscapacity by 50% to 150 megawatts. More localised microgrid structures arealready powering remote locations, like these far-flung islands in SoutheastAsia, and reliable vigor storage. But to ability the world countries with renewable energy, were going to need much more storage than that. 3D printing is seen as a way to reduce thecost of producing solar panels or gale turbines. Ten years ago, the costs of a solar panel installationin the United Regime was $8.50 per watt.Its now $2.99 per watt.Thats a 65% abridge. Harvesting kinetic energy is seen as anotheroption, with some once pioneering engineering that will transform yourfootsteps into electricity. Although the world is changing to renewable energy, fiscal expansion and a developing population entail world vitality demandis still increasing. Not simply do renewables required to comply with the energydemands of today, but likewise tomorrow. Hey people, thanks for watching.
