Since California if it were a country would have the world’s fifth largest economy, and since so many other states are economically integrated with it, this plan, if signed by governor Jerry Brown, could help transform the entire country.
The goal is less difficult than it seems on the surface. California had already committed to getting one third of its electricity from renewables by 2020, and reached that goal in 2017. It committed to getting 50% of its electricity from renewables by 2030, and in fact will likely reach that goal 10 years early, in 2020.
Europe just reached a milestone of one million electric vehicles on the road. Chinese bought 600,000 or so just last year. California is set to become a leader in this area, as well.
California is showing us where the whole country is going, even if some states will take longer to get there. But likely it also will be a big influencer for the whole Pacific Rim. Can Japan really continue its natural gas + nuclear electricity mix once California has shown how easily renewables can supply all our needs? Moreover, California’s efforts will synch with those of China, in ways that will create synergies and thwart Trump’s fossil fuel obsession.
California will save enormous amounts of money by going to green energy, but more importantly, it will rapidly reduce carbon dioxide emissions and show others how to do it, putting a brake on the runaway greenhouse gases that threaten the stability of our natural ecosystems on earth. California is one of the more vulnerable states to the climate crisis.

12.1% Global Renewable Energy Production and Accelerating.(ODT)
The worldwide investment in renewable energy touched $279.8 billion in 2017, taking cumulative investment since 2004 to $2.9 trillion. Globally, the percentage of electricity generated by renewables was at 12.1% in 2017. This reduced carbon dioxide emissions of about 1.8 gigatons as per the UNEP report.

Already, 22% of California’s electricity comes from renewable sources, and lawmakers are considering legislation requiring the state to be 100% green in its power by 2045.It isn’t just California that is swinging into action as the president retreats from our responsibility to avoid climate disaster. Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont will jointly cut power plant emissions by 30% between 2020 and 2030.

Electricity bills are often ludicrously high thanks to our energy-intensive modern world, but every now and then, thanks to the forces of nature, a metaphorical miracle takes place. As reported by Quartz, Germany just experienced such a phenomenon when a particularly bright and sunny day supercharged their solar and wind power sectors.

Poor battery life is the number one complaint when it comes to smartphones and laptops. As a wireless society, having to tether ourselves down to power up our gadgets seems more and more a nuisance. And while researchers are looking into wireless charging, if batteries were better we would have to worry less.

According to a new study from Climatescope, developing nations are far outpacing developed ones when it comes to the installation of new renewable energy infrastructure.
The study monitored 55 developing countries, including emerging economies like China, Brazil, South Africa, India and Kenya, and found that between the years of 2008-2013, developing nations saw 143% growth in renewable energy, versus only 84% in developed countries.
The Climatescope project was originally put together in 2012 by Bloomberg’s New Energy Finance division, the U.K. Government Department for International Development, and the Inter-American Development Bank Group to track the growth of renewable energy in 26 Latin American and Caribbean nations.
This year, they added 19 African countries as well as 10 in Asia to give a wider look at the emergence of renewable energy worldwide.
From 2007 to 2013, those 55 developing countries added a total of 142 gigawatts of renewable energy to their power grids, and more than doubled their total investments in renewable energy, from $59.3 billion to $122 billion.
They also passed a combined 450 legislative measures relating to renewables, according to the Climatescope report.
So why are these developing nations investing in renewables so much faster than the developed world? Well usually it just makes financial sense, according to Ethan Zindler, an analyst in Bloomberg’s New Energy Finance department.
In a phone interview, he used Jamaica as an example. In Jamaica, wholesale power costs about $300 per megawatt-hour. According to Zindler, the country could generate the same amount of power using current solar panel technology for about half that price.
He also added that Nicaragua could similarly cut their costs in half by using wind power (the feature photo of this article is a wind farm on the coast of Lake Nicaragua).
“Clean energy is the low-cost option in a lot of these countries. The technologies are cost-competitive right now. Not in the future, but right now,”
he said.

Although there is some overlap in design features, Solar Roadways’ panels are perhaps more innovative than SolaRoad’s. The US couple’s hexagonal panels are studded with LED lights to make road lines and signs, and also feature heating elements to melt ice and snow.
For the next three years, SolaRoad will test out the path in order to gauge how much energy it is capable of producing and assess safety under different weather conditions. Because it can’t be adjusted to the position of the sun, the panels will generate approximately 30% less energy than those placed on roofs. However, the team anticipates that eventually it should be sufficient to power traffic lights, road lights, houses and electric cars. TNO’s Sten de Wit had a chat with the Guardian about the project, and he believes that up to 20% of the Netherlands’ 140,000 kilometers of road is suitable for conversion into solar roads, which could rake in a lot of energy.
As it’s still early days, production costs are unfortunately rather hefty. The pilot cycle path came with a $3.75 million (€3 million) price tag, which was mostly put up by the local authority. However, as the technology develops and production gets scaled-up, the price should drop.
