Of all the fables created by those who would like to stop solar and wind from taking over the US electricity system, few are as old and as unequivocally false as the canard which states that deployment of variable renewable energy leads to lower levels of grid reliability.
"The greening of the world's electricity system is unstoppable, thanks to rapidly falling costs for solar and wind power, and a growing role for batteries, including those in electric vehicles", said BNEF analyst Seb Henbest, the report's lead author.
These newer generating resources are also contributing to the varied reliability services - such as frequency and voltage management, ramping and load-following capabilities, provision of contingency and replacement reserves, black start capability and sufficiency electricity output to meet demand at all times - that electric grids require to provide electric services to consumers on an around the clock basis.Solar energy has seasonal swings, but with more installations being completed every month and the summer months being the highest generation, we can expect more records for solar generation as April, May, and June data is reported.
Some states did even better than the average ten percent.
Earlier this year, solar energy tariffs in India fell 26 per cent over a period of 3 months, with the current lowest solar power tariff in India standing at Rs 2.44/kWh (3.8¢/kWh).
According to the report, March 2017 saw a marked increase compared to March 2016, which saw wind and solar generate 8.6 percent of total USA electricity. But can wind, solar and hydroelectric power sustain an entire electric grid full-time? However, it's unlikely that renewables will make up the lion's share of energy generation anytime soon, reports Sarah Gibbens at National Geographic.
But within 10 years, coal as an energy source will peak and then decline. This would allow them to save surplus electrical power for later use.
According to Ian Johnston at The Independent, renewable energy is on the rise.
The scenario suggests green energy is taking root more quickly than most experts anticipate. In fact, in several nations, including Denmark, Egypt, India, Mexico, Peru and the UAE, the price of renewables is now cheaper than fossil fuel production.
