Across Asia, companies and governments are adopting more renewable energy as concerns over climate change and carbon emissions move up the development agenda. The Asian Development Bank estimates that the share of renewables in electricity generation in the region will increase from 1.9 per cent in 2010 to 7.1 per cent in 2035.As these new sources such as wind, solar and hydropower become part of the electrical grid, they also introduce instability as energy is produced only under certain weather conditions. Utility operators must therefore find a way to keep the grid stable, says Sven Wagner, Director, ConnectedEnergy at Bosch Software Innovations in a recent interview.
NRELs Integrated Network Testbed for Energy Grid Research and Technology Experimentation (INTEGRATE) will address specific grid integration challenges that allow clean energy technologies to be deployed at scale. The program will demonstrate the use of clean energy technologies to increase the hosting capacity of the grid by providing grid services in a holistic manner and using an open source, interoperable platform. Projects that are part of INTEGRATE will increase the viability, penetration, and deployment of renewable energy technologies by ensuring the reliability and efficiency of electricity generation and use.
Smart metering apps could help make the most of smart grid pilots that will likely take off soon enough.
Electricity generation is one of the eight core infrastructure industries in India and its growth plays a critical role in determining the overall economic growth of the country. Historically, much emphasis has been laid on increasing the installed capacity, which was estimated to be around 259,000 MW in January 2015.
The U.S. Energy Information Administration (EIA) has found that California is the first state to use more than 5 percent utility-scale solar power for electricity generation. Utility-scale power is defined as 1 megawatt (MW) or larger.
According to the report, the solar plants generated 9.9 megawatt-hours (MWh) of electricity in 2014 — 6.6 MWh more than in 2013.
Although solar is becoming an important part of the energy picture in the United States, it remains just a small portion of total electricity generation, according to a report by the U.S. Energy Information Administration (EIA).
According to the December 2014 Short-Term Energy Outlook, solar power generation will only make up about 0.6 percent of U.S. electricity generation in 2015 — which comes out to around 60 gigawatthours a day.
California’s drought hasn’t just left its mark on dried-up fields and suburban lawns. It’s also sapped the state’s supply of hydropower, leaving natural-gas-fired generators — and a growing share of solar and wind power — to make up the difference.
During the first half of 2014, hydropower accounted for only 10 percent of California’s electricity generation, the U.S. Energy Information Administration reported Monday. That’s half the average 20 percent it provided during the first half of every year from 2004 to 2013, as the following chart shows.
Renewable energy, though extraordinarily reliable, cost-effective, and important to the future, is inherently intermittent. Storing and transmitting solar and wind power is the key to scaling the clean energy movement and effecting real changes in the amount of greenhouse gas emissions the world produces.
The smart grid energy storage sector is expected to grow to $50 billion by 2020, with an annual compound growth rate of 8%, according to a recent report from Lux Research. In 2013, renewable energy accounted for only 10% of total US energy usage and 13% of electricity generation, according to the US Energy and Information Administration.
HENRIK LUND of Aalborg University, Denmark, has told the 21st International Congress of Chemical and Process Engineering (CHISA) that Denmark will be able to switch to 100% renewable energy by 2050.
Lund was presenting a plenary lecture at CHISA, in Prague, and said that the switch will require a holistic approach looking at so-called “smart energy systems”, not just considering electricity generation but heating and transport as well. The Danish government’s ambitious target was set in 2006 and includes these three key uses of non-renewable energy. The government has set several interim targets, including that 50% of energy will come from wind by 2020 and that no power plants will burn coal and no households will use oil for heating by 2030.
Australia faces an unprecedented oversupply of energy according to the country’s energy market operator. “For the first time in the history of the National Electricity Market, no new thermal baseload electricity generation is required over the next decade…due to the continuing decline in electricity consumption,” Australian Energy Market Operator said in the report.
That decline is due to a convergence of several factors – greater energy efficiency, more rooftop solar, and the recession that heavily impacted manufacturers who use lots of electricity.
China’s renewable energy capacity increased from 27.8 GW in 2001 to 183 GW in 2013, and alternative sources are expected to account for more than 20 percent of the country’s total electricity generation by 2020, according to research and consulting firm GlobalData. The country’s emergence as a major player in the global renewable energy industry, and the leading country in the Asia-Pacific region, has been accelerated by a combination of government encouragement and market guidance, GlobalData notes.
