The technology of obtaining energy using biogas is simple and cheap. Of course, it also pollutes the environment, but its main problem is the impossibility of generating energy on an industrial scale. This technology is applicable in agriculture on farms, but it is not possible to power a factory, a city or a village from it.

Today the world production of heat, mechanical and electrical energy exceeds 50 trillion. kW / h per year or 5.7 billion kWh per hour. At the same time, more than 80% of the production of all types of energy comes from the burning of fossil fuels - hydrocarbon energy.

We will not talk about hydrocarbon energy - it is expensive, uses limited fuel supplies (oil, gas, coal) and pollutes the environment very much. We consider only three types of electricity generation - nuclear, solar and oxygen.

In line with plans to localise the production of renewable energy in Saudi Arabia as part of its Vision 2030 economic diversification push, seven photovoltaic solar power projects with a capacity of 1.52 GW and worth $1.51bn (SAR5.6bn) were launched on the side-lines of the recently concluded Saudi Elenex exhibition.

The Dubai Electricity and Water Authority (DEWA) and a consortium led by Saudi Arabia’s ACWA Power and the Chinese-government owned Silk Road Fund have completed financing of the 950 MW fourth phase of the Mohammed bin Rashid Al Maktoum Solar Park, it was announced on Sunday.

EIA - Renewable generation provided a new record of 742 million megawatthours (MWh) of electricity in 2018, nearly double the 382 million MWh produced in 2008. Renewables provided 17.6% of electricity generation in the United States in 2018.

PLATTS- Germany added almost 3 GW of solar capacity last year, the highest annual figure since 2013 and 68% more than 2017, German solar association BSW said Thursday. Total installed solar PV capacity was 45.929 GW by end-2018, with 377 MW added in December alone.

REUTERS - Pumping carbon dioxide into the air makes the planet greener; the United Nations puts out fake science about climate change to control the global energy market; and wind and solar energy are simply “dumb”.

PLATTS - Germany has added over 2 GW of new solar capacity over the past year as the rebound for the sector accelerates and annual additions are on track for the strongest growth since 2013, the latest monthly data from the federal grid regulator showed

WNN - The Digest of UK Energy Statistics (DUKEs), published today by the Department for Business, Energy and Industrial Strategy (BEIS), shows low-carbon sources of electricity accounted for a record 50.1% of power generated in the UK in 2017, which is up from 45.6% the previous year. This figure consists of 21.0% from nuclear, 14.8% wind (onshore and offshore), 3.4% solar and 2.3% hydro amongst low-carbon power sources.
