In the last 10 years, hundreds of tribal groups across the US have adopted renewable energy like solar and wind as a way to serve their community needs better.
The type and size of the solar installation depends on the needs and goals of each community. Each group has adopted it in unique ways, from large utility-scale projects where the tribe leases land to a developer, to small solar-plus-storage systems designed to provide electricity to rural homes that are too distant to connect to the electric grid.
Reasons and goals vary among tribes. Some desire greater independence from the utility, while others want to set a higher standard of living for local residents through greater financial independence. Others want to bring electricity to rural households. But one goal is shared: to adopt an energy source that offers clean, renewable electricity.Continue reading
It’s easy to forget that electric trains are a type of EV, and possible to power with clean energy like solar.
According to a peer-reviewed paper just published at Nature Climate Change; “Future cost-competitive electricity systems and their impact on U.S. CO2 emissions” – the cheapest way to radically cut greenhouse gas emissions from generating electricity by 2030, would be a high-voltage direct current (HVDC) grid connecting America’s prime renewable resources to 256 electricity markets.
Before the vote was taken at the town meeting, various residents expressed some pretty wild ideas about the mysterious “powers” of solar.
A husband and wife, Jane and Bobby Mann, were the most irrational.
Small Pacific islands, like Tokelau, with its tiny population of just 1,500 souls, are generally dependent on the most expensive and dirty – and unreliable energy there is.
With so few people living in such isolated islands, their choices have been limited to diesel generators.
Musk is not alone. The climate scientist Jim Hansen also believes that a global carbon tax is the most effective policy driver of a clean energy economy.
The idea is that only a carbon tax will accelerate the move to a clean powered economy. Similar to the tax on cigarettes but not on fruits and vegetables, this would be a revenue-neutral tax; ie, taxes would be lowered elsewhere in the economy so that government treasuries would receive the same as they do now.
The City of Las Vegas has filed a request with the Public Utilities Commission (PUC) of Nevada to get power from part of a 100-MW solar farm that SunPower is developing in Boulder City for the state utility NV Energy.
Solar is getting cheaper fast.
Globally, 70 gigawatts of renewable energy was installed in 2013, and that cost $279 billion. In 2014, almost 40% more was installed and yet that didn’t cost 40% more – it actually cost nine billion less than even the year before; $270 billion.
Iowa’s Cedar Falls Utilities (CFU) has launched a community solar garden that its electricity customers can buy into, with the opportunity to purchase units of the energy output from the solar array.
Goldman Sachs said that it is going to invest $150 billion in clean energy projects. This would represent a fourfold increase in the amount of money it plans to invest in financing clean energy infrastructure around the world.
