Who is leading in renewable energy? | CNBC Explains

All around the world, governments are building more solar commons, wind raises and hydroelectricpower plants to generate power. As global warming and climate changecontinue to make centre stage, which countries are extending in generatingpower through renewable energy? And what are the challengespreventing mass adoption? In 2018, more than a part of the worldsenergy was generated from renewable sources, thanks to costs coming down andmore green programs taking off. Renewable energy cancome from many sources. 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 insignificant city-state. And not all countries have the samepotential to harness empty force or the right environment forcertain energy infrastructure. Let’s take a look at whosleading the vigour revolution.China, the United Nation, Brazil, Indiaand Germany have the biggest renewable influence ability worldwide, in no small segment due to their size. Remove hydropower from the concoction andGermany moves up to number three and Japan takes thenumber five recognize. But its no accident that these six countries alsomake the schedule of the worlds biggest power customers, meaning that even if they were producingrenewable energy at ability, it was better sees up a small proportionof their overall force mix.Divide renewable supremacy faculty 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 force concoction. Nordic and Latin American countrieshave a good showing on this list. More than 75% of Norway, New Zealand, Brazil andColombias energy production comes from renewables. Venezuela, Canada, Sweden andPortugal also make a good show. But for big-hearted lubricant producing 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 surroundings.Norway has 1,660 hydropower plants andmore than 1,000 storage tanks. It is possible for Norway to depend on hydropowerbecause of the countrys long coastlines, steep depressions 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 electricity is also derivedfrom around 3,600 hurricane turbines.Likewise in Brazil, which has flows and huge swathesof the Amazon rainforest within its borders. Clean energy, including hydropower, accountedfor 42% of its electricity production in 2017. Ditto for Colombia and Venezuela, countries known for hydroelectricity. One famous cautionary falsehoods about over-reliance onone form of renewable energy comes from Venezuela, which depends heavily on the Guri dam forabout 60% of “the two countries ” electrical needs. In 2010 and 2016, droughts motived the barriers sea tofall so low-spirited, the government had to declare emergencies. So where does the energyrace disappear 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 disappointments since. The United Regime will withdraw from the ParisClimate Accord. So were getting 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-wide force mingle 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 atmosphere neutral economy. But most renewable energy sources are stillsubject to irregular pressures of mood. Imagine a drought rendering a embankment uselessand taking out a countrys sole electricity supply. Or sporadic exertion from windor solar beginnings. What then? Thats where innovation andnew technologies kick in. Remember when billionaire Elon Musk tweetedthat he would lay a battery storage method in South Australia within1 00 daylights, or deliver it for free? The Tesla battery system now accommodates the titlefor the largest lithium-ion battery in the world.It can currently store 129 megawatt-hours of energy from air turbines by renewablepower company Neoen. This is enough to meet theneeds of 30,000 dwellings. Now, Neoen has plans to upgrade itscapacity by 50% to 150 megawatts. More localised microgrid plans arealready powering remote locations, like these far-flung islands in SoutheastAsia, and adding reliable power storage. But to power the world with renewable energy, were going to need much more storage than that. 3D etching is seen as a way to reduce thecost of producing solar panels or wind turbines. Ten years ago, the cost of a solar panel installationin the United District was $8.50 per watt. Its now $2.99 per watt.Thats a 65% reduce. Harvesting kinetic energy is seen as anotheroption, with some previously pioneering technology that will transform yourfootsteps into electricity.While the world is changing to renewable energy, fiscal emergence and a originating population aim world power demandis still increasing. Not exclusively do renewables have to meet the energydemands of today, but too tomorrow. Hey people, thanks for watching.
