The Endless Power of the Ocean

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.”

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.”

Renewable energy is all around you

perovskite-crystal“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.

Geothermal power increasing in California

Diversifying our power supply is key

geothermal-power-plant-in-californiaRenewable Energy Analyst and Research Projects Manager of the Geothermal Energy Association, Benjamin Matek, reports that “Last fall, the California legislature passed SB 350, a bill that will increase the state’s renewable energy generation to 50 percent by 2030 utilizing resources like wind, solar, biomass, and geothermal energy. This goal will be a first. No large-scale economy like California has ever attempted to transition to a grid powered in majority by renewables.

 

UGE vert axis wind turbine2-examStudy after study on the California energy landscape point toward the same answer: make the grid diverse. California’s grid will require a mix of renewable resources like solar, hydropower, storage, wind, and geothermal. For example, a study commissioned by the Walton Family Foundation on a 50 percent renewable grid found that “replacing 10 TWh of solar PV with geothermal . . .  reduces CO2 emissions by 4.2 million metric tons per year in California and 2.4 MMT/yr in the rest of the West.”

America is growing more energy independent!

flintridRenewable Energy World, one of the leading publications in the RE business just ran an encouraging story about the RE market.

“Renewable energy accounted for the majority (50.5 percent) of new U.S. electrical generation put into service during the first 11 months of 2016, according to the latest issue of the Federal Energy Regulatory Commission’s (FERC) monthly Energy Infrastructure Update (with data through Nov. 30, 2016).

biomass-power-plant1Combined, newly installed capacity from renewable sources (i.e., biomass, geothermal, hydropower, solar, wind) totaled 9,655 MW, surpassing that from natural gas (8,109 MW), nuclear power (1,270 MW), coal (45 MW), and oil (33 MW) combined.

 

wind-power1The rapid growth of renewables — particularly solar and wind — has resulted in their seizing an ever-growing share of the nation’s total generating capacity. Five years ago, renewable sources cumulatively accounted for slightly over 14 percent of total available installed generating capacity; now they provide almost 19 percent (18.69 percent): hydropower, 8.53 percent; wind, 6.58 percent; solar, 1.84 percent; biomass, 1.41 percent; and geothermal, 0.33 percent.”

Massachusetts adopts bill for massive wind and hydropower projects

Massachusetts flag“The comprehensive energy bill adopted this week by the Massachusetts legislature includes a provision requiring the state’s utilities to enter into long-term contracts to purchase both offshore wind and hydropower by 2027.

 

offshore_wind_energy in Virginia 2015In addition to the 1,600 MW mandate for offshore wind, utilities would have to purchase an additional 9.45 million MWh of power annually from new Class I resources and hydropower,” writes Jennifer Delony, Associate Editor of Renewable Energy World magazine.

This move toward clean energy will create jobs and help keep the environment livable.

New York is getting charged up!

According tNey York flago our friends at Renewable Energy Magazine, “Mayor Bill de Blasio, the Mayor New York City, has announced the launch of the NYC Clean Fleet – a comprehensive plan to create the largest electric vehicle (EV) fleet of any US city.

PriusThe Clean Fleet plan will cut municipal vehicle emissions in half by 2025 – and 80 percent by 2035 – and serve as a model for the private sector and other 21st century cities in fighting climate change.

The proportable car charging stationsject is the latest in a series of ambitious but necessary climate initiatives outlined in the Mayor’s OneNYC plan which sets a long-term goal of reducing all greenhouse gas emissions across New York City by 80 percent by 2050. Currently, the transport sector accounts for nearly one-quarter of citywide greenhouse gas emissions.”
