Hawaii is on course to achieve its carbon neutrality goal

In 2015 the Aloha state expressed its commitment to going completely renewable and carbon neutral by 2045, the most ambitious goal in the US. Hawaii is expected to reach those goals as the state’s main utility company is reaching the final steps of a deal to add seven new solar-plus-storage projects to the island, representing the largest infusion of renewable energy and storage capacity in the state. Each of the solar projects will be connected to a storage system that is expected to provide at least four hours of stored electricity per day.

Global demand for fossil fuels will peak in 2023, says thinktank

Global demand for fossil fuels will peak in 2023, an influential thinktank has predicted, posing a significant risk to financial markets because trillions of dollars’ worth of oil, coal and gas assets could be left worthless. Explosive growth in wind and solar will combine with action on climate change and slowing growth in energy needs to ensure that fossil fuel demand peaks in the 2020s, Carbon Tracker predicted.

The desolated scene of Chernobyl is producing energy once more

After suffering the world’s worst nuclear disaster in 1986, the land surrounding the Chernobyl nuclear plant has been devoid of human settlement and was thought to remain like this for another 24,000 years. In 2016, however, Ukrainian official came up with the idea of installing a solar farm on the uninhabited area. Now the land is home to 3,800 solar panels capable of powering energy into 2,000 households. This is just the beginning as Ukraine has granted nearly 6,200 acres of land to solar investors that could be turned into a giant solar plant.

30 percent of the world’s energy supply to be clean by 2023

The latest annual report of the International Energy Agency suggests that the world will install over 1 terawatt of clean energy within the coming five years. That’s more than the entire power generation of the European Union today. The expected growth is made possible by a rise in the number of solar, wind, and hydro installations as well as more accommodating government policies. The new forecast also expects solar energy capacity to rise threefold, overshadowing bioenergy to become the third largest source of renewable energy.

Wider use of clean energy would reduce power outages during storms

In those moments when we were all experiencing “the calm before the storm,” we could not yet know the impact Hurricane Florence would have on our state, but we were certain it would be significant. In its aftermath, Florence indeed left a devastating mark on some of North Carolina’s already-vulnerable communities.

New, cheaper battery will boost energy storage in developing countries

Clean renewable energy requires power storage in batteries. The lithium-ion battery is the most efficient one. The technology is also expensive which limits their impact in developing countries. An innovation by a US energy company might change that. NantEnergy is developing a zinc-air battery that is considerably cheaper than other battery types currently on the market. Compared to lithium-ion battery costs estimated to be between $300 and $400 per kilowatt-hour, the zinc-air battery has cut cost down to less than $100 per kilowatt-hour.
