Hydropower is the world’s most widely used green energy


UK-based industrial technology and products company RS Components has carried out an analysis of data from the US Energy Information Administration to find out the most popular green energy sources per every country in the world and the states producing the most of each type of renewable energy.

Hydropower occupies the first place as the most-favored option by a huge margin. 122 of the countries analyzed generating most of their renewable energy from this source. China is the winner for hydropower, at 1,145.5 billion kWh, that is above Caada and Brazil, the second and third largest producers with 388.6 billion kWh and 367.2 billion kWh, respectively as reports.

China is home to the world’s largest hydroelectric gravity dam, the Three Gorges Dam, and the country produces over a quarter of the world’s installed capacity. 

China tops the field as producer of hydropower, solar, wind, and biomass. The US is “top performer” in geothermal with 15.9 billion kWh, with geothermal power plants present in seven states in 2019, despite hydropower being the country’s main green energy source overall. But geothermal power is the least popular source of energy — it’s the main renewable source for only the Philippines, Kenya, and Nicaragua.

Solar and wind sectors are growing at a high speed.

Solar and storage trends

Online solar and energy storage marketplace EnergySage has presented its 11th semiannual Solar Marketplace Intel Report analysing new trends in solar and storage. Here are three main trends:

Solar prices continue to decrease, but at a slower rate: The first half of 2020 experienced the median quoted solar price dropping 1.4% over the second half of 2019. However, the 2.4% decrease between July 2019 and June 2020 is a slower rate of decline than seen in previous 12-month periods.

Tesla’s Powerwall 2 is the most quoted and least expensive storage option on EnergySage. Over half of the energy storage quotes on EnergySage include the Tesla Powerwall. It’s followed by LG Chem’s RESU 10H. On a cost per kilowatt-hour basis, the Powerwall 2 is also the least expensive storage option being quoted.

Resilience drives interest in energy storage. Nearly two-thirds of customers are driven by wanting backup power, which isn’t surprising in the face of more frequent and intense weather catastrophes such as wildfires and hurricanes that knock out power. Further, nearly 50% of EnergySage shoppers that want storage are interested in financial savings.
