What makes hydropower so reliable?

E-mail Print PDF

Hydropower is renewable energy source with a very long history of use. In fact, the world's first hydroelectric power plant began operating in 1882, on the Fox River in Appleton, Wisconsin. One extremely important factor that makes hydropower so reliable is the longevity of hydroelectric power plants.

According to the Energy Information Administration (EIA) hydroelectric power plants are the oldest power plants still in use in United States with the average operating time of the hydroelectric facility in United States being 64 years.

EIA recently reported that the 50 oldest electric generating stations in the U.S. are all hydroelectric power plants, all of which have been operational since 1908.

Despite this longevity and reliability, hydropower still only accounts for approximately 7 percent of U.S. electricity generation each year.

How can renewable energy help rural areas?

E-mail Print PDF

Despite the fact that we live in 21st century, in the age of computers and a variety of high tech gadgets, there are still more than 1.2 billion people on the planet who do not have access to electricity. These people mostly live in isolated and rural areas that are not connected to the main electric grid. Is renewable energy solution to electricity in these areas?

The answer is yes, in this I firmly believe. And the solution to this issue lies in micro-scale power generation. Renewable microgrids are the most efficient solution to these areas.

Many countries could provide small power grids for their isolated and rural communities. The power would originate from renewable energy sources such as hydro, wind or solar.

These communities do not require large and expensive power stations but rather renewable energy powered microgrids to provide enough power for people that live in these areas.

Fossil fuels will soon be overpowered by renewable energy

E-mail Print PDF

Yes, fossil fuels such as coal and oil still rule the global energy market and renewable energy source still cannot satisfy ever-growing demand for power. But there are many positive signs that things could change in not so distant future.

Climate change cause is often mentioned as the main driving force behind the recent surge in renewable energy technologies. This is only partially true because renewable energy technologies are becoming increasingly relevant in one area that really matters - cost-competitiveness.

Take solar power for instance. The recent report from Guardian says that the cost of solar power have dropped by staggering 85% in the last seven years. Wind power is also becoming cheaper, there are more and more electric vehicles in the roads, and things are really shaping nicely for global renewable energy industry.

New York City To Go For More Renewables

E-mail Print PDF

New York City could soon make switch from nuclear power to renewable energy sources and improved energy efficiency as a three-unit Indian Point Energy Center nuclear power plant is scheduled to be completely shut down by 2021. 

This plant has a capacity of more than 2,000 MW and went online in 1970s. Governer Andrew Cuomo has labeled this plant located just 30 miles from the Big Apple a "ticking time bomb" and made efforts to shut it down as soon as possible.

Governor Cuomo recently announced how he has persuaded plant's owner, a Louisiana-based Entergy to shut down reactors by 2021. According to reports the owner will bear the costs of decommissioning and the state will in turn withdraw all the legal challenges against the plant.

The emphasis on how to replace power from nuclear reactors should be on renewable energy sources coupled with improved energy efficiency. However, some energy experts doubt that this plant could be replaced without using more fossil fuels.

Japan's solar energy future still uncertain

E-mail Print PDF

It is very difficult to predict the future solar energy development in Japan. After the Fukushima accident the Japanese seemed to abandon nuclear energy and turn to solar and other renewables as replacement options. Since 2012, Japanese government also introduced feed-in-tariffs which forced electricity providers to buy power from renewable energy suppliers.

This opened the door for many large solar energy projects such as massive floating solar farm near Tokyo which should power approximately 5000 average Japanese homes in 2018. 

However, the government support for solar energy seems to be waning in Japan and Tokyo's long-term's commitment to renewables looks seriously in doubt because government is looking to kickstart nuclear energy back in the mix even despite the public perception.
