I found an interesting article on “The Pros and Cons of Biofuel” and thought you might like to read it.
“There are many environmental benefits to replacing oil with plant-based biofuels like ethanol and biodiesel. For one, since such fuels are derived from agricultural crops, they are inherently renewable—and our own farmers typically produce them domestically, reducing our dependence on unstable foreign sources of oil.
Additionally, ethanol and biodiesel emit less particulate pollution than traditional petroleum-based gasoline and diesel fuels. They also do not have much of a net contribution of greenhouse gases to the global climate change problem, since they only emit back to the environment the carbon dioxide that their source plants absorbed out of the atmosphere in the first place.” Source: https://www.thoughtco.com/the-pros-and-cons-of-biofuels-1203797?utm_term=biofuels+journal&utm_content=p1-main-1-title&utm_medium=sem&utm_source=msn_s&utm_campaign=adid-f612939a-48bb-43e7-a324-12ce60486b63-0-ab_msb_ocode-35517&ad=semD&an=msn_s&am=broad&q=biofuels+journal&o=35517&qsrc=999&l=sem&askid=f612939a-48bb-43e7-a324-12ce60486b63-0-ab_msb
Block Island Wind Farm
This May, the 2,000 residents of Block Island, Rhode Island are making a fresh start when it comes to powering their lives. As of May 1, Block Island is the first location in the U.S. to be powered by an offshore wind farm — a wind farm that has eliminated the need for a diesel plant that was burning about one million gallons of dirty diesel fuel annually. According to the Environmental Protection Agency (EPA), diesel produces more carbon emissions than every other fossil fuel except for fuel oil.
The Block Island Wind Farm is intended to bring significant change, and not just on Block Island. The project was designed to serve as an example of the tremendous potential that offshore wind power holds for the United States. The Office of Energy Efficiency and Renewable Energy (EERE) has created a wind resource assessment and characterization study, which depicts this potential.- Excerpt from an article by Karla Lant
Geothermal energy is heating up in Nevada!
In July 2016, US Geothermal began drilling at their San Emidio project in Nevada. “They drilled to a depth of 1,000 feet and encountered high bottom hole temperatures and high temperature gradients. Both of those findings are indicators of a deeper, active geothermal system, the company said, adding that, if productive zones are encountered, the wells will be tested to determine resource temperature and production characteristics in the area.
Phase I of the San Emidio project was completed in 2012, when an existing 3.6 MW plant was replaced with a more efficient 9 MW power plant.”
Think about it, the ocean is moving 24/7/365. Between the waves and the tides, there is a constant source of renewable energy being generated, but not being harvested. “Generating technologies for deriving electrical power from the ocean include tidal power, wave power, ocean thermal energy conversion (OTEC), ocean currents, ocean winds and salinity gradients.
Of these, the three most well-developed technologies are tidal power, wave power and ocean thermal energy conversion. Tidal power requires large tidal differences which, in the U.S., occur only in Maine and Alaska. Ocean thermal energy conversion is limited to tropical regions, such as Hawaii, and to a portion of the Atlantic coast. Wave energy has a more general application, with potential along the California coast. The western coastline has the highest wave potential in the U.S.; in California, the greatest potential is along the northern coast.
California has more than 1,200 kilometers (745 miles) of coastline, and the combined average annual deep water wave power flux is over 37,000 megawatts (MW) of which an upper limit of about 20 percent could be converted into electricity. This is sufficient for about 23 percent of California’s current electricity consumption. However, economics, environmental impacts, land-use and grid interconnection constraints will likely impose further limits to how much of the resource can be extracted.
Although technology is still at a relatively immature pilot project stage, economic projections indicate that ocean energy could become cost-competitive over the long-term.”
Here are three reasons why natural gas is more expensive than geothermal energy:
- It is consumable (consumed in the process of creating heat)
- Combustion heating creates Green House Gas emissions
- It is subject to carbon taxes
Meanwhile, geothermal heat pumps are the opposite of natural gas:
- Geothermal is renewable (the solar energy stored in the earth is continually replenished)
- Geothermal creates no Green House Gas emissions (no combustion on site)
- Geothermal isn’t charged carbon taxes, so it’s more affordable.

Don’t lose heart my dear ones, here is a snippet showing our blog stats for today! Not only do we have a great showing for this post, it’s from all over the world.
And it’s delightful!!!!!
PS. I know it looks hazy, but click on the jpg and it will show you the details in full.
Solar power is big business!
In an article from PV TECH, I read that “The route to decarbonisation in the energy sector will create benefits of US$10 trillion every year by 2050, while requiring only US$1.8 trillion to implement, according to a new joint report from the International Energy Agency (IAE) and the International Renewable Energy Agency (IRENA).
In their first ever collaboration, IEA and IRENA found that a total of 6 million jobs would be created, even when accounting for jobs lost in other industries.
Further jobs will also be created in the energy efficiency sector. The report stressed that efforts on the transition need to be stepped up urgently to stay in line with the targets of the Paris Agreement.
IRENA director-general Adnan Z. Amin, said: “Critically, the economic case for the energy transition has never been stronger. Today around the world, new renewable power plants are being built that will generate electricity for less cost than fossil-fuel power plants. And through 2050, the decarbonisation can fuel sustainable economic growth and create more new jobs in renewables.”
“Many forms of energy surround you: sunlight, the heat in your room and even your own movements. All that energy — normally wasted — can potentially help power your portable and wearable gadgets, from biometric sensors to smart watches.
Now, researchers from the University of Oulu in Finland have found that a mineral with the perovskite crystal structure has the right properties to extract energy from multiple sources at the same time.”- from Science Daily
