Earth Energy Advisors Monthly Energy Report - Even as renewables increase, fossil fuels continue to dominate U.S. energy mix:Source: U.S. Energy Information Administration, Monthly Energy Review – July 3rd 2017 Fossil fuels have provided more than 80% of total U.S. energy consumption for more than 100 years. Since 1928, when consumption of natural gas surpassed that of biomass, the three fossil fuels—petroleum, natural gas, and coal—have been the most consumed fuels in the United States. In 2016, fossil fuels accounted for 81% of total U.S. energy consumption, the lowest fossil fuel share in the past century. In 2016, the renewable share of energy consumption in the United States was 10.5%. This was the largest renewable share since the 1930s, when overall energy consumption was lower and the amount of biomass consumption (mainly wood) was relatively high. The greatest growth in renewables over the past decade has been in solar and wind electricity generation. Liquid biofuel consumption—more than half of which is ethanol blended into motor gasoline—has also increased in recent years, contributing to the growing renewable share of total energy consumption. In addition to the increasing share of renewables, the decline in the fossil fuel share of consumption is attributable mainly to declines in coal consumption. U.S. coal consumption fell nearly 9% in 2016, following a 14% drop in 2015. Overall, U.S. coal consumption has declined almost 38% since 2005. In each of the past 20 years, the power sector has accounted for more than 90% of total U.S. coal consumption. Petroleum, which encompasses nearly all transportation fuels and several petroleum-based fuels used in homes, businesses, and industries, continues to be the largest source of energy consumption in the United States. Petroleum consumption has increased in each of the past four years. Consumption of natural gas has risen in 9 of the past 10 years. As recently as 2006, the United States consumed more coal than natural gas (in energy-equivalent terms), but as natural gas consumption has increased—particularly in the electric power sector—natural gas use in 2016 was about twice that of coal Source: EIA June 18th publication “Today in Energy Source: EIA April 18th publication “Today in Energy”

Earth Energy Advisors Monthly Energy Report- Monthly renewable Electricity generation surpasses nuclear for the fist time since 1984 In March, and again in April, U.S. monthly electricity generation from utility-scale renewable sources exceeded nuclear generation for the first time since July 1984. This outcome reflects both seasonal and trend growth in renewable generation, as well as maintenance and refueling schedules for nuclear plants, which tend to undergo maintenance during spring and fall months, when overall electricity demand is lower than in summer or winter. Record generation from both wind and solar as well as recent increases in hydroelectric power as a result of high precipitation across much of the West over the past winter contributed to the overall rise in renewable electricity generation this spring, while nuclear generation in April was at its lowest monthly level since April 2014. However, EIA’s latest Short-Term Energy Outlook (STEO) projects that monthly nuclear electricity generation will surpass renewables again during the summer months of 2017 and that nuclear will generate more electricity than renewables for all of 2017 Source: EIA June 18th publication “Today in Energy

Earth Energy Advisors Monthly Energy Report Conventional hydroelectric generation, which remains the largest source of renewable electricity in most months, totaled 30 billion kilowatthours in March, the highest level in nearly six years. Largely because of record precipitation and snowpack in California, EIA’s latest STEO projects an increase of 14% for hydroelectric power in 2017 compared with 2016. Electricity generation from wind and solar has increased as more generating capacity has been installed. More than 60% of all utility-scale electricity generating capacity that came online in 2016 was from wind and solar technologies. These sources contributed to record high levels of generation from both fuels: between March 2016 and March 2017, wind generation increased by 16%, and solar generation increased by 65%. In April, solar generation continued to increase, while wind generation fell slightly. EIA’s STEO projects an increase of 8% and 40% in wind and solar utility-scale generation, respectively, in 2017. As renewable generation has increased, net generation from nuclear power has remained relatively flat since the late 1990s. Retirements of a number of nuclear plants have resulted in a slightly lower level of overall nuclear generation capacity, and in turn, a lower level of generation. Unlike generation levels from wind and solar, which follow seasonal patterns that reflect the fluctuations in their resources, monthly fluctuations in nuclear generation largely reflect maintenance schedules. Based on data reported to the Nuclear Regulatory Commission and compiled in EIA’s daily Status of U.S. Nuclear Outages report, an average of 14 gigawatts and 21 gigawatts of nuclear capacity were offline during March and April, respectively, representing about 14% and 21% of total nuclear capacity in the United States.

Earth Energy Advisors Monthly Energy Report Natural Gas Market Update The natural gas rig count rose by 5 to 189 active rigs in the past week.   Storage is now at 2.89 Tcf, with this week's storage report coming in higher than anticipated. Stocks are now 187 Bcf above the 5-year average.   Prices were down across most of the nation this week, with the exception of Southern California which saw price increases due to extreme hot weather forecasts Source: EIA June 18th publication “Today in Energy
