Biofuels

By Andy May – Re-Blogged From WUWT

According to Exxon-Mobil, 9% of the world’s energy came from biofuels in 2017. They do not expect this percentage to increase by 2040, and it may go down. For the most part it is a developing world fuel. Primary biofuels include dung, wood, wood chips and pellets. Secondary, or manufactured biofuels include ethanol and biodiesel, which derive from several agricultural products, mainly corn, sugar cane, palm oil, soybeans and canola. The main advantage of using locally sourced wood and dung are their low cost and wide availability.

Using imported wood or wood chips for generating electricity, as is done in Europe, is more problematic. Due to the economic and environmental costs of farming the trees, making the wood pellets or chips and shipping them to the powerplants; wood is not a competitive fuel for most powerplants. The energy density is too low. However, if the source of the wood is within fifty miles of the plant, it can be competitive with coal and it may produce fewer greenhouse gases than coal, estimates vary. Ethanol and biodiesel are also more expensive than fossil fuels and must be subsidized to be competitive.

Brazil Set To Post Record Harvest

From The GWPF – Re-Blogged From WUWT

Brazil’s 2019-20 grain and oilseed crops are poised to reach record production of 245.8mn metric tons (t), boosted by an increase in acreage and a recovery in the soybean crop, which will also likely break a record.

The number would mark an increase of 1.6pc from the last cycle. The total area planted is also expected to reach a record of nearly 64mn hectares (158mn acres), up 1.1pc from last year’s season, the country’s agricultural statistics agency (Conab) said today in its first report on the new season.

Farmers have already started planting soybean and corn in some southern and west-central areas of the country. Both commodities – including the winter corn crop, sowed after the soybean harvest – account for 90pc of all Brazil’s grain and oilseed crops. Other crops included in the total are sunflower, barley and peanuts, among others.

Quote of the Week: “There are some ideas so wrong that only a very intelligent person could believe in them.” – George Orwell [H/t John Dunn]

Number of the Week: 2012

Beauty in Physics: On his web site, The Reference Frame, string theorist Lubos Motl had a long post reporting his search for the terms beautiful, beauty, and pretty in the Feynman Lectures on Physics (1963). Richard Feynman was a co-recipient of the 1965 Nobel Prize in Physics for his work in Quantum Electrodynamics and an exceptional lecturer who insisted on teaching students introductory physics. Perhaps it is his expression of finding exceptional explanations of complex problems beautiful that makes Feynman’s lecturers so memorable. Fortunately, they are available to read online. One of the many examples Molt gives is on Kepler’s laws:

Here are the promised Kepler’s laws.

Palm Oil – A Gift or a Curse?

Re-Blogged From WUWT

Oil palm is alternatively seen as a gift from god or a crime against humanity; according to science, it is neither

Oil palm is neither the devil’s work, nor a godsend to humanity. Its effects on its surroundings largely depends on case-specific circumstances. Those who ask to boycott all palm oil due to its contribution to deforestation should also consider boycotting coffee, chocolate and coconut if they wish to be consistent.

Palm Oil Was Supposed to Help Save the Planet. Instead It Unleashed a Catastrophe

By Paul Homewood – Re-Blogged From WUWT

This is a long, but very readable piece from the New York Times Magazine:

I have only included the opening section, plus a few relevant paragraphs, but I would recommend reading it in full:

The fields outside Kotawaringin village in Central Kalimantan, on the island of Borneo, looked as if they had just been cleared by armies. None of the old growth remained — only charred stumps poking up from murky, dark pools of water. In places, smoke still curled from land that days ago had been covered with lush jungle. Villagers had burned it all down, clearing the way for a lucrative crop whose cultivation now dominates the entire island: the oil-palm tree.

China in Water Crisis

By Eric Worrall – Re-Blogged From WUWT

China’s environmental and food logistics problems may be far worse than they are letting on.

China’s hunger for soybeans is a window into an encroaching environmental crisis

BY JEFF NESBIT

How China’s desperate efforts to source soybeans from all over the world is explained by the country’s fear of running out of water.

China approached Peru and Brazil with an extraordinarily ambitious proposition several years ago. It would build a 3,000-mile railroad from the western coast of Peru to the eastern coast of Brazil to handle commerce and trade from the interior of South America to China.
