World Energy Attitude Shifts

According to a report by the International Energy Agency (IEA), in 2016 the global economy grew and carbon dioxide emissions from energy production did not. In fact, the IEA found worldwide carbon dioxide emissions have remained the same for three years.

Progress is uneven but promising. China reduced emissions 1% last year, and India just passed tougher auto emissions standards in March, 2017. Where lower priced alternatives to coal have encouraged countries to switch to natural gas, renewable power sources, and nuclear energy. carbon dioxide output has declined or stabilized. In every country, improved energy efficiency has helped the environment in terms of carbon dioxide reduction and less deforestation. In Malawi, for example, rural and urban consumers have been willing to consider replacing traditional three-stone fires with an investment in clay, metal, or thermoelectric stoves that burn charcoal more efficiently than charcoal and much more efficiently than wood.

The growing concern about climate change has stimulated the search for green energy alternatives. In Norway, the Ocean Sun company is working on solar farms that can float on the ocean and transmit power back to crowded urban areas. Others are looking into technology for floating wind turbines, for generating power from hydrogen, and for using the hydropower of waves, tides, and rivers.

 At its gold mines in Suriname and Burkina Faso, Toronto-based IAMGOLD is using solar energy to reduce the use of diesel oil that generates greenhouse gases. The company sees the hybrid diesel solar photovoltaic engine, built by the Finnish group Wartsila at its gold mine in Burkina Faso, not only as a way to make an environmental contribution to the world but also as a way to reduce energy costs, protect against fuel price volatility, and increase local employment.

Efforts to convert the power of Atlantic Ocean waves into energy in the Orkney Islands north of the Scottish mainland and at the Wave Hub facility in Cornwell off the far southwest coast of England have been less successful. Besides the prohibitive cost, tricky engineering problems and the need to develop new materials capable of withstanding storm stresses and corrosive salt water require solutions. A device needs to handle the variety of pounding storms and normal waves, up and down motions, and wave speeds. Navigation needs to avoid these devices. And biologists view the moving parts of underwater turbines as a threat to sea mammals, fish, and diving birds. Yet, the UK's European Marine Energy Centre in the Orkneys attracts tests by Wave-tricity's Ocean Wave Rover and Finland's Wello Oy Penguin. Australia's Carnegie company has been financing CETO's Wave Energy Technology which has placed giant buoys off the coast of Cornwell in an attempt to produce emission-free energy and desalinated freshwater.  

Diamond Flaws

President Obama will visit one kind of diamond, when he takes in a baseball game in Cuba this week.* And June brides have a many-faceted diamond on their ring fingers. For the independent miners paying the violent armed groups who control access to the rivers in the Central African Republic (CAR), the diamonds they find represent a treacherous way to scrape out a living.

     These miners are far removed from those who wear the diamonds and gold found in the CAR, Zimbabwe, Burkina Faso, Angola, and Mexico and the precious stones from Afghanistan and Myanmar (Burma) and from those who rely on the mobile phones, cars, computers, and other products that contain tungsten from Colombia and tantalum, tungsten, and cobalt from the Democratic Republic of the Congo. Before these raw materials become part of finished products, they change hands often in secretive and poorly regulated supply chains that span the globe.

     The UN, OECD, US, and EU all are taking measures to pressure companies to ask their mineral suppliers more questions and to notice warning signs. Berne Declaration, a Swiss non-governmental organization (NGO), knew Togo produced little or no gold, yet Swiss companies thought they were buying gold that originated there. Instead, their gold was coming from Burkina Faso. True to its advertising, De Beers is assuring consumers "a diamond is forever" by launching a pilot program to buy diamond jewelry and loose diamonds for resale, thereby reducing the need to buy new diamonds from unknown sources.

     Not only is there growing concern about the human rights abuses associated with the dangers independent miners face, but conflict in the world's poorest countries relies in part on financing from selling licenses to miners, collecting tolls on transportation routes to the mines, taxes, and mineral sales. In Zimbabwe, even the national security forces and secret police supplement their government budgets and escape government oversight by engaging in the mineral trade.

     There are money and jobs enough in the mineral trade for both miners and manufacturers to benefit by behaving responsibly.
