From plants to people, every living thing on this planet needs water. But getting enough to survive, and survive comfortably, that can be a little tricky. Just look at the furor around California’s new water restrictions. If a state as wealthy as California is having to get creative in order to start saving water, you can bet that governments and municipalities with less money and clout are having to turn to even more inventive methods to get clean water without breaking the bank.

Luckily, some of the brightest minds in the world are on the case. USAID recently announced the winners of the Desal Prize, part of a competition to see who could create an affordable desalination solution for developing countries. The idea was to create a system that could remove salt from water and meet three criteria: it had to be cost-effective, environmentally sustainable, and energy efficient.

The winners of the $140,000* first prize were a group from MIT and Jain Irrigation Systems. The group came up with a method that uses solar panels to charge a bank of batteries. The batteries then power a system that removes salt from the water through electrodialysis. On the most basic level, that means that dissolved salt particles, which have a slight electric charge, are drawn out of the water when a small electrical current is applied. In addition to getting rid of salt (which makes water unusable for crops and for drinking), the team also applied UV light to disinfect some of the water as it passed through the system.

Using the sun instead of fossil fuels to power a desalination plant isn’t a totally new idea. Larger solar desalination plants are being seriously investigated in areas where water is becoming a scarce resource, including Chile and California. While proponents hope to eventually could provide water to large numbers of people, the technology is still expensive (though prices are dropping) and requires a lot of intricate technology.

In rural areas or developing countries, durability is key, and technology that requires constant upkeep won’t last long. The MIT/Jain team and their competitors tested their projects at the Brackish Groundwater National Desalination Research Facility in New Mexico, where they had to run the system for 24 hours at a time, removing salt from 2,100 gallons of water each day. The next step is to test it in an even harsher environment, exposing it to everyday use with rural farmers in an area where USAID is active. If all goes well, the system could provide enough water to irrigate a small farm.

THE Office of Utilities Regulation (OUR) will this Friday host a pre-bid meeting to provide further information on its recent Request for Proposals (RFPs) from interested entities, to provide new Generating Capacity from renewable energy sources.

The meeting will take place at the Jamaica Pegasus hotel and interested entities are urged to attend to get more information on this project, and get clarifications where needed.

Applicants are invited to submit proposals to provide new generating capacity amounting to net 37 megawatts (MW) of electricity generation from either or both firm capacity and energy-only technology from renewable energy-based power generation facilities on a build, own and operate basis. The submission date for applications is January 27, 2016.

The OUR issued its latest RFP on July 31, 2015, as it moves to conclude a project started in 2012 to identify a total of 115 MW of generation projects from renewable sources.

Three bidders were selected then, for energy only projects totalling 78MW. They are Blue Mountain Renewables LLC, to supply 34MW of capacity from wind power at Munro, St Elizabeth; Wigton Windfarm Limited, to supply 24MW of capacity from wind power at Rose Hill, Manchester; and WRB Enterprises Inc (now Content Solar), to supply 20MW of capacity from Solar PV from facilities in Content Village, Clarendon. The 78 MW identified through these three suppliers was subsequently increased to 80.3 MW.

The OUR was requested by Cabinet to complete the procurement of the additional 37MW from renewable energy sources. The details of the RFP has been posted on the OUR’s website.

THE Inter-American Development Bank (IDB) and University of Technology (UTech) recently collaborated on a one-day workshop designed to teach non-technical professionals about the energy sector and how it affects their lives and businesses.

Billed ‘Demystifying the Energy Industry’, the event targeted business people, entrepreneurs, banking and insurance executives, among others. It zeroed in such areas as energy costs and renewable alternatives to fossil fuels.

IDB Country Representative Therese Turner-Jones noted that “because energy is a complex and technical topic, discussions are often dominated by energy sector professionals”.

But the workshop, she said, would help non-technical professionals “navigate discussions involving issues like petroleum-derived fuel products, natural gas, wind, solar, waste-to-energy, biofuels and energy efficiency”.

Dr Ruth Potopsingh, associate vice-president of Sustainable Energy at UTech noted that “knowledge of the energy sector can better equip us all to make sound business decisions”.

IDB Consultant Dr Earl Green presented the results of the IDB/DBJ Energy Efficiency Pilot Projects for Small & Medium Enterprises and a video called Success Stories in Energy Efficiency in Jamaica.

Lumas Kendrick Jr, senior energy specialist, IDB, moderated a panel discussion on Finding Solutions for Jamaica’s Energy Sector Challenges, which included panellists Fitzroy Vidal, director of energy, Ministry of Science, Technology, Energy & Mining; Christopher Brown, business development manager, Development Bank of Jamaica; Dr Ruth Potopsingh, associate vice-president-Sustainable Energy, UTech; and IDB/DBJ Grant recipients Yorkin Waltes, owner, Triple Seven Farms and Pauline Wilson, general manager, Pioneer Meats.

Google Maps is already one of the most popular apps used on on smartphones thanks to its sophisticated navigation powers. But Google has figured out an even cooler use for the service and it that doesn’t even involve getting directions – meet Google’s brand new Project Sunroof.

Using the immense map data that’s behind Google Maps, the company’s new Google Maps feature will help you decide the best way to install solar panels on your roof. What Google can do for you is use the knowledge it collects about your home’s location to tell you how much sunlight you’re getting each day, how much electricity that can generate and how much it’ll cost you to install the solar panels.

Basically, Google’s service will be ready to answer some of your most pressing questions related to installing solar panels on your roof. So all you need to do is jot down the data and get ready to invest in solar panels for your roof. We should note, of course, that solar power might not be a good investment for everyone so make sure installing them will be financially worthwhile before making the switch.

Project Sunroof will debut in Boston, San Francisco and Fresno, but should expand to other markets in the future. A video explaining the cool Google Maps tech behind it follows below – more details about the project are available on Google’s special site for it at this link.

No AC? No problem! With these hacks, you can keep cool this summer — and keep your electric bill down.

When the temperature creeps past 90 degrees on a hot summer day, it’s natural to regret the decision to rent a place without air conditioning or own a home without AC installed. But don’t despair. With these tips for living without an air conditioner, you can stave off the sweltering heat without paying a sky-high utility bill (or putting in a noisy, energy-sucking window unit).

1. Change the rotation on your ceiling fan to counterclockwise.

It’s easier than you think to make this fix (usually your fan will have a little switch on the motor housing that alters its rotation), and doing so will allow the blades to circulate faster, creating a cooler breeze. If you have box fans, turn them around so that they blow hot air out the window.

2. Don’t let the light in.

Keeping shades, curtains, or blinds closed can lower the temperature inside your house by up to 20 degrees.

3. Channel your inner MacGyver.

Create a misting effect by placing a metal mixing bowl full of ice in front of a fan. Tilt the bowl so that the fan blows directly onto the ice. When the air hits the cubes, it will release a cool, misty breeze that chills the whole room.

4. Don’t close yourself off.

By shutting doors, that is. Keep inside doors open throughout the day, which allows the cool air to circulate throughout your house.

5. Revamp your bedding.

Pack away the flannel sheets (duh) and opt for percale instead, which is more breathable. Mist your sheets with cool water before bedding down for the night (or stick them in the freezer for a few minutes), and invest in a buckwheat pillow, which won’t trap heat the way traditional pillows do.

6. And then sleep solo.

Your partner may balk, until he or she realizes how much body heat cuddling creates.

7. Hit up your hot water bottle.

Only this time, stick it in the freezer first and then position it near your feet, which contain many pulse points. If you don’t have a hot water bottle, dunk your feet in ice water before turning in.

8. Unplug.

Appliances that are plugged in radiate heat — even when they’re not in use. So unplug what you can. Now is also the time to embrace your grill; turning on the oven on a 100-degree day is only going to make things hotter. But you knew that.

9. Turn off the lights.

Even the most energy-efficient light bulbs give off some heat, so make do with natural light on super-hot days. But still swap out incandescent bulbs for CFLs, which will also lower your energy bill. 

10. Lie low.

Literally. Hot air rises, so putting your mattress on the floor can help you stay cool while you slumber. Or if you’re feeling outdoorsy but like sleeping with a roof over your head, rig up an indoor hammock, which will increase airflow. Bonus: It may even lull you to sleep, which will make you forget how hot you are.

The U.S. Department of Agriculture (USDA) has announced $63 million in loans and grants for 264 renewable energy and energy efficiency projects nationwide.

USDA is supporting these projects through its Rural Energy for America Program (REAP), which was created by the 2008 farm bill and was reauthorized by the2014 farm bill.

These newly funded projects are expected to generate and/or save 207.8 million kWh of energy – enough to power more than 13,600 homes for a year.

“This funding will have far-reaching economic and environmental impacts nationwide, particularly in rural communities,” says Agriculture Secretary Tom Vilsack. “Investing in renewable energy and energy efficiency projects supports homegrown energy sources, creates jobs, reduces greenhouse gas pollution and helps usher in a more secure energy future for the nation.”

Eligible agricultural producers and rural small businesses may use REAP funds to make energy efficiency improvements or install renewable energy systems, including solar, wind, renewable biomass (including anaerobic digesters), small hydroelectric, ocean energy, hydrogen and geothermal.

Since the start of the Obama administration, USDA has supported more than 9,600 renewable energy and energy efficiency projects nationwide through REAP.

The next application deadline for REAP grants is Nov. 2. In the coming weeks, USDA will issue a notice of available funding with more details on how to apply.

 

Solar Industry Mag

Throughout the entire first half of 2015, solar and wind energy accounted for 2,518 megawatts of new electricity generating capacity brought online in the US— some 65 percent of all new capacity added so far this year.

Coal accounted for a mere 3 MW during that time period, while natural gas accounted for 1,173 MW (there was no new oil). That’s less than half the amount of solar and wind energy added January to June. Wind alone, at 1,969 MW, was more than all fossil fuels combined.

Here are the full numbers from the Federal Energy Regulatory Commission’s latest Energy Infrastructure Update:

 

“With Congress now debating whether to extend the federal tax incentives for renewable energy sources, it is reasonable to ask whether the American public has gotten a good return on these investments to date,” Ken Bossong, Executive Director of the SUN DAY Campaign, said in response to the update. “The latest FERC data confirms that the answer is a resounding ‘Yes!’”

Despite the tangible economic and environmental benefits of their huge growth in recent years, the US solar and wind industries are still facing a looming threat due to uncertainty over federal tax incentives.

The Senate Finance Committee just approved a tax bill that would reinstate the wind production tax credit (PTC), which expired on January 1, 2014 after Senate Republicans basically killed it. ThinkProgress reports the renewed tax credit would be worth $10.5 billion over 10 years and would last through December 31, 2016.

Fossil fuels are estimated to receive $135 billion in federal subsidies over the next decade from the US government, so it’s understandable that investors are weary of the long-term prospects of wind and solar, which, despite on-again, off-again support from the federal government, still must fight for every bit of market share they can get.

The two renewable energy technologies combined still only represent less than eight percent of total installed capacity in the US, after all, compared to natural gas at 42.66 percent and coal still hanging on at 26.83 percent, per the FERC data.

Which is why environmentalists and wind energy supporters want Congress to go further by adopting a more long-term solution.

“Wind power is gaining strength but in the context of tax extenders, this Congress must extend the PTC and [the investment tax credit] for the longest possible time to avoid pushing American wind power off a cliff,” the American Wind Energy Association’s Jim Reilly told ThinkProgress.

The solar industry is expecting a surge in business as a variety of investment tax credits are set to expire at the end of 2016. Without any further action from Congress to promote the clean energy technologies of the future, however, the surge is guaranteed not to last.

The Ministry of Agriculture and Fisheries, through the National Irrigation Commission (NIC) is set to introduce the use of solar power to operate the pumping of water for irrigation.

Minister of Agriculture, Labour and Social Security Derrick Kellier says the move will commence shortly with the commissioning into operation of solar power to operate the pumping system at Ebony Park in Clarendon.

In September a $300 million irrigation project will be launched at Spring Plain/Ebony Park bringing the nearly 3,000-acre property at the agro-park into full production.

Kellier, who was speaking at the 63rd Annual Denbigh Agricultural, Industrial and Food Show in Clarendon on Saturday, August 1, said that if Jamaica is to increase its production and productivity and ensure its food security, irrigation systems needed to be significantly improved and expanded.

Noting that the total irrigable land in Jamaica is 187,814 hectares yet only 12,500 hectares or about seven per cent of that land is irrigated, Kellier outlined a number of strategies intended to optimise and expand the country’s irrigation systems.

The imperative to optimise and expand the country’s irrigation systems is not born solely from the scarcity of water, but from the imperative to increase productivity and Jamaica may very well reach the stage where fiscal incentives for investment in irrigation had to be provided, Kellier said.

The agriculture ministry was therefore preparing a comprehensive proposal to be discussed with the appropriate authority, he added.

“I believe we have no alternative since these droughts are the greatest threat to increased production,” said Kellier.

According to the ministry, in addition to various climate-smart and drought mitigation projects, over $5 billion has been spent over the past 10 years to install new irrigation systems to ensure sustainable agriculture and the reduction of dependence on rainfall.

Two years after failing to find qualified bidders to deliver 37 megawatts of firm renewable energy capacity, the Office of Utilities Regulation (OUR) has returned to the market seek suitable investors.

However, this time around it is willing to take bids for electricity that is generated intermittently – such as when the sun is out or as the wind blows – rather than guaranteed power being made available to the grid.

Waste-to-energy projects, including the conversion of the Riverton dump into a fuel source for such a plant, was seen a means of providing firm capacity in the past.

But only one of the 28 bids that went after the requests for proposal to build 115MW of renewable capacity (of which 78MW would be energy only) was related to biomass.

Two of the proposals received then were wind projects and 25 were for solar energy.

In the end, Wigton and BMR Jamaica were chosen to build a combined 60MW of wind capacity and Content Solar Jamaica Limited was picked to develop a 20MW photovoltaic solar farm in Clarendon.

“None of the bids submitted in respect of firm capacity, made it through all the stages of the evaluation process to be accorded preferred bidder

status,” said a release from the regulator in 2013.

Bidders for the latest RFP will be evaluated on the same grounds as the last time – 20 per cent weighting will be given to experience, while ability to finance the project carriers a 35 per cent weighting across stage 1 evaluation scores.

Bidders have up until January 27, 2016 to submit their proposals, along with a US$8,000 ($940,000) non-refundable application fee. A pre-bid meeting is scheduled for August 28.

The regulator is aiming to evaluate bids; negotiate contracts between the power providers and Jamaican Public Service Company; and see the chosen bidder start construction of the new plant by July 2017 for a December 2018 commissioning date.

The OUR will give an additional year for firm capacity plants to be commissioned.

JPS currently supplies consumers from an installed system capacity of approximately 945.1MW, of which 300.6MW is provided by independent power providers.

In 2014, annual generation from renewable energy sources accounted for approximately six per cent of total system generation, with contributions of 2.5 per cent and 3.5 per cent from hydro and wind, respectively.

 

The Gleaner

Hundreds of businesses including eBay, Nestlé and General Mills have issued their support for Barack Obama’s clean power plan, billed as the strongest action ever on climate change by a US president.

The rules, announced on Monday, are designed to cut emissions from power plants and have been strengthened in terms of the long-term ambition as originally proposed by the president last year, but slightly weakened in the short-term in a concession to states reliant on highly-polluting coal.

White House adviser Brian Deese said the Environmental Protection Agency (EPA) rules represented the “biggest step that any single president has made to curb the carbon pollution that is fuelling climate change”. The US is the world’s second biggest carbon emitter after China.

The rules are expected to trigger a “tsunami” of legal opposition from states and utilities who oppose the plans, which will significantly boost wind and solar power generation and force a switch away from coal power. Republican presidential hopefuls moved quickly to voice their opposition, saying they would be economically damaging.

But 365 businesses and investors wrote to 29 state governors to strongly support the rules, which they said would benefit the economy and create jobs.

Mindy Lubber, who is attending the launch ceremony of the rules on Monday and is the president of Ceres, a network of investors that organised the letter, said: “The clean power plan is the right measure at the right time. It’s a flexible, practical and economically sound blueprint to transition America toward a low-carbon future.”

Other signatories included Unilever, L’Oréal, Levi Strauss, Staples, renewable energy company SunEdison and Trillium Asset Management, which manages $2.2bn in assets. It is the largest group of businesses to support the rules so far.

The final rules propose a 32% cut in carbon emissions from power plants by 2030 on 2005 levels, up from the initial proposal of 30%. However states will only have to comply by 2022 rather than 2020 as originally proposed, and will be able submit their plans on meeting the targets by 2018 instead of 2017.

CO2 emissions from power plants fell 15% between 2005 and 2013, meaning the country is halfway to the target.

Monday’s version of the rules also gives an explicit boost to wind and solar power, angering the natural gas industry which will still be a large beneficiary of the switch from coal to gas-fired power plants, which produce much lower emissions.

America’s Natural Gas Alliance, a trade body, said it was “disappointed and discouraged” by the rules. The World Coal Association claimed the plan “will significantly increase the cost of electricity to American consumers.” The Solar Energy Industries Association, on the other hand, said the rules were “historic” and “critically needed”.

The new rules will give a “give a head start to wind and solar deployment”, according to a White House fact sheet. “Drive more aggressive investment in clean energy technologies than the proposed rule, resulting in 30% more renewable energy generation in 2030 and continuing to lower the costs of renewable energy,” it said.

Barack Obama, in a video address, emphasised the health benefits of reduced air pollution from coal plants, and a duty to future generations as reasons for the clean power rules.

“Power plants are the single biggest source of the harmful carbon pollution that contributes to climate change. But until now there have been no federal limits on the amount of that pollution those plants can dump into the air. Think about that,” he said.

Obama’s plan to bring in the rules to cut emissions from power plants – which account for a third of the US’s greenhouse gas emissions – date back to 2009 when the EPA declared carbon emissions a public danger, the first step towards regulating them.

The final rules are likely to be welcomed by the United Nations, which is hosting a climate summit in Paris at the end of the year to agree on a deal on post-2020 curbs on emissions, as well as financing to help poorer countries manage global warming. Laurent Fabius, the French foreign minister, issued a statement welcoming the regulations.

Andrew Steer, president and CEO of the Washington DC-based thinktank the World Resources Institute, said: “The clean power plan should reassure international partners that the US administration is determined to deliver the 26-28% emissions reductions promised for 2025.

“Our analysis suggests that this rule can be implemented without technical or financial impediment, and in a manner that is likely to promote more, not less, economic prosperity.”

Describing the rules as very important, Lord Stern, the author of an influential review of the economics of climate change, said: “It shows the determination of the world’s richest country to maintain better economic growth while also cutting greenhouse gas pollution. President Obama has recognised in particular the enormous damage caused by pollution from the burning of coal in power stations.”

Gina McCarthy, the EPA’s administrator, said she believed the agency was on strong legal grounds for defending the rules from the legal challenges they are almost certain to face.

“Over the next few days we will hear the same tired old plays from the old special interests playbook,” said McCarthy.
