US cities determined to be 100% renewable energy users

Despite Trump's resolve to take the world back to the dark ages (yep, even darker than now!) many cities in the USA with Republican mayors are dedicated to becoming 100% renewable energy based (mostly solar) as soon as possible. p { margin-bottom: 0.25cm; line-height: 120%; }a:link { } Renewables 100 Policy Institute assists municipalities, regions and other stakeholders with mapping their

worlds largest floating solar power plant

In China, the city of Huainan in the Anhui province, the 40-megawatt solar power plant facility was created by PV inverter manufacturer Sungrow Power Supply Co.   Poetic? The lake is sited over a former coal mining area. Incidentally, there are many species of fish that are happy to live in shade.  Full story:  china floating solar-power plant Related: renewable energy storage ,

Solar PV - clean energy, wobbly finance

Mixed news on solar generation of electricity On the one hand, buyers of homes are steering clear of homes with leased solar PV panels on the roof, because of uncertainty and complications surrounding the owners of the panels - a private company, and the guarantors of the tariffs - government. It's hardly news that a week is a long time in politics, so a twenty five year guarantee of feed in

Solar energy to produce hydrocarbons from climate change pollutants

Recent breakthroughs in semiconductor physics have produced the possibility of using solar energy (photovoltaic generation) to capture CO2 (carbon dioxide) from the atmosphere, but, most importantly, to do so where it is being produced by industrial use of carbon based fuels which currently contribute to climate change pollution. Using DC electricity to electrolyse water into Hydrogen and

Projected Global Growth of renewable energy

The 2015 Paris Climate Agreement from Business for Social Responsibility, a nonprofit organisation that works with companies to develop sustainable business strategies, takes a look at where clean energy investment is globally today and where it is expected to be over the next two decades. They predict that the world could get over 30% of its energy from renewables sources by 2030.

energy policy for a sane species

Imagine that the human race was capable of consideration for others, rationality and honesty. What would the world's energy supply look like? The most recent estimate of global energy consumption is for 2013 - 5.67 10^20 joules A kilowatt hour is 1000 x 60 x 60 joules = 3,600,000 joules = 3.6 10^6 joules. So energy consumption is approximately 2.10^14 kilowatt hours per year. For those

1.2 gigawatt offshore wind farm

Currently the world's largest offshore wind farm has been given the go ahead in the North Sea, 75 miles east of Hull, England. The 1.2 gigawatt (1,200,000 kilowatts) is expected to generate enough power for one million homes. Wind power is crucial for the UK, as we experience more wind in the winter when solar power is minimal. The Danish firm Dong Energy is investing in the project, and

Solar power inverters - efficiency and self-reliance

Tata, the car manufacturer (and more) and one of the first to make a budget electric car, now has an offshoot called Tata Power Solar. It is releasing a solar PV unit that stores electricity from PhotoVoltaic panels in batteries to power an inverter (to mains AC) to replace the domestic mains when there is a power cut. This is designed for helping customers in remote and poor areas where

new solar thermal material

A new solid state material has been developed that stores daylight in a solid state form (like batteries) without the need for expensive batteries.  It can be triggered to release the energy as heat on demand, so simple applications such as harvesting energy during the day to heat the building after dusk are proposed Research is proposed that explores extending the lifetime of storage (

Solar PV progress

The Journal of Renewable and Sustainable Energy has published a report on the problems of merging large scale PV (photovoltaic) solar energy generation with existing AC (alternating current) distribution systems (like to your home and businesses). Dependence on PV to a large extent causes problems associated with daylight being limited, which is easy to manage (other sources of energy are timed

Renewable energy storage

A 5 megawatt Li-Ion battery storage facility has been opened in Oregon, U.S.A. It is only a demonstration project, as the cost of storing excess energy from renewable sources such as solar and wind generation is still not a practical solution. This demonstration is part of a micro-grid - a local grid that stores energy for the local community, and it can even provide power when the national grid

Electric car charging in Manchester

Manchester UK now has 250 electric car recharging points. The charging facilities are free, at the moment, in a drive to get more commuters committed to buying an electric vehicle or converting an existing one.

Solar farms in Egypt

Annual Solar Energy input to Earth With an average level of solar radiation between 2,000 to 3,200 kWh per square metre a year, Egypt has significant potential for solar energy. To date, however, uptake of solar projects has been slow because of high capital costs, but the country has recently moved to expand its solar capacity. 3,000 kWh over 365 days would power a well-designed, energy
