Carbon offsets via forest protection [REDD] are mostly myth

REDD-Monitor : "It is entirely untrue that all 13 of the projects have stable tenure over forest lands. Several of the communities have entirely collapsed with no practical management over forest lands. 15 year agreements with the Forestry Administration which can be revoked at any time, and which in practice have been entirely undermined by the presence of the Royal Cambodian Armed Forces in no way constitutes secure tenure. There are now entire villages located within core project forests which community members have been powerless to stop. A large tract of the largest community forest area is also to be submerged by a Chinese built dam, yet the temporary forest agreements were ignored."

Using methane hydrate for fuel a deadly mistake

BBC News: "Quite apart from reaching them at the bottom of deep ocean shelves, not to mention operating at low temperatures and extremely high pressure, there is the potentially serious issue of destabilising the seabed, which can lead to submarine landslides.

A greater potential threat is methane escape. Extracting the gas from a localised area of hydrates does not present too many difficulties, but preventing the breakdown of hydrates and subsequent release of methane in surrounding structures is more difficult.

And escaping methane has serious consequences for global warming - recent studies suggest the gas is 30 times more damaging than CO2."

Subsidizing carbon emissions and calling it carbon neutral

World Economic Forum: "Needless to say, it does not make economic sense to import eight million tons of wood pellets yearly across the Atlantic Ocean. However, the British government has provided over $1 billion in annual subsidies to utilities to pay the cost of pellet production and transport."

Autonomous vehicles mean more sprawl

CityLab : "One school of thought on autonomous vehicles holds that they’ll increase traffic and sprawl: Without expensive fuel and the soul-gnawing investment in time wasted commuting behind the wheel, people will feel the pain of driving less, live even further away from urban centers, and basically use robot-cars for all manner of frivolous pursuits."

Electric car direct subsidy $7,500 per vehicle

Cars promote sprawl and growth. Cars and car infrastructure are subsidized. Growth is the biggest threat to the biosphere. Electric cars are just another excuse to subsidize growth.

dailykos: "Most of us Nissan Leaf drivers got our cars via a Nissan lease deal. It’s a win-win: Nissan gets its Leafs out the door, bags the $7500 Federal rebate, plus some of the car’s value from us (as down/monthly payments), then gets the car back in 2-3 years to sell it again. Meanwhile, because Nissan factors the full $7.5k into the lease deal, we get a much cheaper lease than for comparable ICE cars, and can partake in the EV revolution without the risk of getting stuck with a badly depreciated, outdated tech product."

65% energy lost before wheel turns on electric car

sciencedirect: "The WTW efficiency for EVs running electricity derived from a stationary power plant is shown in Fig. 4. Natural gas from the pipeline is fed into the stationary power plant, which has an electrical generating efficiency that depends on the type of power plant. The electricity is then distributed to the grid, where it is subject to T&D losses resulting in a WTP efficiency of between 28% and 45% depending on the power plant technology. Electricity is transferred to the EV via a charging station, which is on the order of 85–95% efficiency. The battery-to-wheel efficiency of an EV over a drive cycle can range from about 79 to 91% depending on how regenerative breaking is accounted for [41]. This gives an overall WTW efficiency of between 22% and 35%."

#Renewableenergy is a cover for energy-subsidy and growth

Greentech Media : "The Trump administration will need to enact policies that would help de-risk these investments, maintain the United States’ technological competitive advantage, and bring the best, most efficient and advanced technologies to bear to power the American economy. As a starting point, they can draw on the innovative financial models developed by U.S. green banks. These institutions can provide the Trump administration with a model for creating economic growth through visionary, effective financial innovation."
#Renewables mean growth, growth means heat, heat means clathrates will melt. When that happens emissions will far surpass what was saved by renewables.
